Comparing SX50 1200mm shot to SLR crop

The Nikon 1 blog and the comment about the Pentax Q make it clear that there is an opportunity to build a camera/lens combo that would take most of the market away from the APS-C or FF when used with big glass.  At this point it really would be as simple as a Nikon 1 native zoom lens at 100-400mm (almost 1200mm equiv), which could be much smaller, and less expensively better quality, than the FF glass.

I haven't read that blog article, but if you look at what's currently available it looks less attractive.

If you chose camera's with a 10x zoom (about 28-300mm FF equivalent), I find that 1 inch (Nikon 1), m43 and APS-C (NEX) sensor systems are actually all in the same range regarding weight, and the size isn't that different either. Even an APS-C entry level DSLR with 10x zoom would be just 15-20% heavier - a good trade for a realtime viewfinder etc. The bigger sensor systems sometimes have slightly brighter (not dimmer) lenses and certainly better DOF isolation.

Maybe Nikon 1 has lenses that are less optimised for size and more for quality and AF speed (don't know, just a thought), and of course having an additional WA to standard zoom range makes the design more difficult. But still ... I think a 1 inch system with long telezoom would only be really small when using a very dim zoom. And even for bird photography etc. small DOF is sometimes very important... And on the other side, a system like Panasonic FZ200 without the WA to standard zoom range could be smaller too, probably while offering a constant f/2.8.
