Well. From 43 Rumors we can read this.

Composing with a viewfinder is much more natural, not to mention the stability benefits of holding the camera to your eye, and ability to keep both eyes open while looking through a viewfinder to track moving subjects. There are plenty of reason to use an OVF/EVF even with the best rear LCD you can possible imagine.

I'm not an "oldie" either, I started shooting with digital cameras, so....

The "arms length" thing just isn't conducive to most photography, sure using the rear screen is great to get at odd angles, but a VF is much better when it comes to composing your shots.
