  • Bigger body, more materials.

Which makes the A6000 lighter to carry.

Still doesn't escape the fact that more materials means a greater cost.

  • Better build quality with weather sealing.

Weather sealing is nice. But the build quality of the A6000 is pretty decent.

Personal opinion versus fact.  Also, decent doesn't mean it is better.

  • IBIS.

Lens based OSS works better than IBIS.

Debatable.

  • Higher resolution EVF.

A6000's EVF is just fine.

Again, personal opinion versus fact.

  • Better LCD screen (RGBW vs RGB).

I'm an 100% LCD guy myself, and I would appreciate that. I can set the LCD of the A6000 to "outdoor" more, but at times I wish it was brighter.

  • LCD screen has more articulating points.

LCD screen of the A6000 is done just fine.

Again, personal opinion versus fact.  What is just fine for you may not be enough for someone else.

  • Dedicated PDAF sensor allows continuous AF even while the shutter is in action.

A6000's sensor based PDAF keeps up just fine, even at full burst

Again, personal opinion and it still can't do what the A77II can.  Since the PDAF is directly on the sensor, it cannot focus during exposure whereas the A77II which should give it an advantage in tracking.

  • Higher frame rate.

12fps vs 11fps? Pretty much the same.

True, but facts are facts and it is a higher frame rate which puts a higher demand on the camera.

  • More buttons, dials, and inputs.

A6000 has plenty of button. Also, its menu layout is very good, and the Fn function is very helpful.

Still doesn't avoid the fact that more buttons, dials, and inputs add more to the cost due to extra materials.  Some prefer most of their settings to be mapped to buttons than menus too.

  • Faster max shutter speed (1/8000s vs 1/4000s).

True, but how often would you need faster than 1/4000s though?

Your personal opinions are really driving this away from the facts.  Again, higher shutter speed means more demand on the hardware.  As for how often it is used, while not often I do find it indispensable when I do need it.  So, thus, it is a requirement for me.

  • Greater flash sync speed (1/250s vs 1/160s).

Is that really important?

Again, opinion versus facts.  Maybe not for you, but for many others it is.  I find it very important when I do my studio work.

  • More powerful built-in flash.

True, but the A6000 needs less flash power due to its better sensitivity. Besides, it's much more fun to avoid flash altogether using a focal reducer with a fast legacy lens. Eg. a 50mm f/1.4 lens becomes a 35mm f/1.0 lens... That's bright where you can avoid flash in pretty low light conditions.

Wow, that is such a load of crap.  Sorry, but that is the lamest excuse to justify a weaker flash (especially for a sensitivity difference of .5 stops or less).  The flash power rating for both cameras are rated at the same ISO speed.  The fact is a more powerful flash allows a longer reach at any given ISO as well as the ability to provide more fill, even at base ISO.

While I prefer not shooting with flash, it comes in handy in those situations where you have no other choice.  Even then I prefer a dedicated flash.

As for your fast lens excuse, besides the fact you need an adapters to shoot with anything faster than F/1.8, a large aperture is not always the answer to shoot in low light since you sacrifice depth of field and, for many lenses, sharpness.

  • Probably a longer shutter life (150,000 vs speculated 100,000).

Nah.

Nah as in you think the shutter life is the same or nah that you don't care?

While they may be the same, it has been typical of Sony's lower end cameras to have shutters that are rated for only 100,000 clicks while their higher end cameras are closer to 150,000 clicks.  I was listing the possibility of a difference which would add to the cost of the camera.

There are probably a few other things I am missing, but this is a quick run down.

The A6000 with 18-105 f/4 G lens is a great combination. The video is awesome on it. Very low light video capabilities, and you can set the aperture from wide open to like f/10+ and still retain continuous auto focus. For stills, the number of pdaf + cdaf auto focus points are very high and they're *all* over the frame. You can select wide area continuous focus mode which capture super high action very effectively. There are a bunch of other new things, that the A77ii may or may not have. Lock on AF with shutter for instance. What happens there is you focus on an object, after which is starts tracking it automatically and it won't lose it anywhere in the frame. You can then recompose and burst at your heart's content. The subject can move closer or further, and the continuous AF will track it perfectly, even at 11fps shooting.

The A77 and the A77ii already have a capability like that called object tracking.  A square pops up on the screen and you select the object you want to track.  Once selected, the camera will attempt to keep the object in focus as it moves around the screen, even towards and away from the camera.  Nothing new.

The A77ii may be also a great camera, but it's not going to crush it by any means.

A77ii versus A6000, different horses for different courses.

To sum it up:

Sorry, those are weak counterpoints that have nothing to do with what the OP was asking.

The OP was asking what are the differences between the two that may contribute to the cost difference.  All you did was lay down your opinion of what YOU find useful or not and not what is actually better or more costly that contributes to the price difference.
