If I had to guess... it's because those who "need" 30mp are in the extreme minority when you look at the whole scheme of things. I, personally, do not look forward to the days of 35-50mp file per RAW photo.
The thing is, Canon implements smaller RAW formats on their cameras these days, so you can choose to shoot at lower resolutions if you want, and gain the per-pixel noise advantages of doing so. For some strange reason, the resulting files aren't as small as one might expect, and I don't know why that is.
Sure, if you're a big-time photog w/ need for MP... well, you might already be shooting w/ MF anyway and don't really care about what Canon would/might offer.
The thing is that higher resolution gets you greater flexibility, as long as you're not trading it for something critical (like speed). The 7D manages 18 megapixels at 8 FPS. The 1DX manages the same at 12 FPS. That suggests that a high resolution 1DX could manage 27 megapixels at 8 FPS if Canon wanted to go that way.
The problem is that Canon hasn't yet implemented a camera where the speed of the camera scales inversely with the selected resolution, so up to now, at least, it has always been a tradeoff between maximum resolution and speed.
Furthermore, while I agree that people who must have the most resolution are likely to be shooting medium format, one could argue the same thing about crop versus full frame. The fact of the matter is that full frame is generally going to be cheaper than medium format, and there's quite a lot of benefit to that.
Canon killed the 1Ds line probably because the next iteration would have been in the price range of medium format cameras, but hitting the same disadvantages relative to medium format that crop has relative to full frame. Which is to say, it would be a flop in the target market.
Canon wants to make a camera where they can sell the most units and make the most profit.
Exactly. Which is why the 1Ds line doesn't make any sense at a $10K price point.
So here's my question for those who want more MP. Would you all be happy with Canon if they shoehorn a 30-35mp sensor into the body of a 5D2 and relabeled it 5D3? Would you be willing to upgrade and pay the $2500-2700 asking price if the camera kept its not-too-stellar AF the way it is?
Hell no. But that's because I'm after a really good all-purpose camera. The 5D2 doesn't qualify.
If not, then would you then pay $8000 for a 30-35mp sensor into the 1DsIII and called it the 1DsIV? (if Canon had not already announced the 1D X)?
I'm not paying $8k for any camera, nor $7k for that matter. But if I were in the target market, that might be worth it. It would be less than the price of medium format, would get me enough resolution that I might be able to compete with it to some degree, and would get me a nice fat selection of lenses to choose from.
As I see it, Canon's damned if they did, damned if they didn't. What couldn't you shoot w/ a 1DsIII @ 21mp that you think you can magically capture with 30mp?
Landscapes? People claim the 7D isn't good enough for landscapes at 18 megapixels. Why would 21 be?
