Eh. I don't know. What does "really big print" mean? Sure, there's a market, but there comes a point where the market is so tiny it doesn't count when it comes to ultimate sales. While 30mp is probably far beyond what I need (20x30 max print in my world... which prints fantastically from my lowly 5D mark III), when does a 46 vs 30mp image really start to make a difference? I have no idea. Probably doesn't make any difference at all for the vast majority. Might make a big difference to somebody that crops a lot. So yes, my needs. Problem is that a lot of people who say they need it really don't. It's kind of like buying a car that will do 200mph. We can do that, but then never go above 90mph. So what's the point of the other 110 possible mph? There really is no point except to say that we can if we really want to.
The high end camera will probably add megapixels, but for my needs? Don't care. There's a point where mp are just a status symbol and not a functional necessity. To be honest, 99.99% of what I do is on the web anyway, so I could get by on far less than what I have. That's probably true of most. Not saying higher mp would turn me off from buying. Not at all. Just that it isn't a big consideration. The bigger consideration for me would be whether the high end camera ergonomics were right. Others have different wants. Wants and needs are two different things.
