Quote: In the same way that film developed over the years with finer detail the same will happen to sensor design . Photography is big enough church to accommodate all what ever size of sensor. Lets not forget marketing and advertising. How much quality do you really need? There a lot of FF hype out there. When was the last time a picture editor, competition judge or RPS assessor asked when looking at an image. Is it FF.? They don't because it doesn't matter, its the picture that counts.

Yes and no - certainly some picture libraries (Getty springs to mind) have a list of approved cameras in much the same way as they used to not accept 35mm film, or only Velvia if they did. Are they right to? Well, that's up to them, really, but you have to assume that they know their business.
But for me, the reasons I prefer the larger format aren't really much to do with ultimate image quality (although that's nice), but more to do with the greater control I have over DOF effects and in particular, differential focus - and on the other hand, it's nice with a smaller format to have more DOF at times. There are strengths and weaknesses for most of the currently available sensor sizes (not sure that Canon's APS-H still has much validity, though) and it's really a case of selecting a format whose characteristics match your requirements best.
