I'm afraid they will show nothing significant. The lens will be the star. They got caught with their pants down by the Nikon 800e. I think they were ready to show some stuff but it was outclassed when Nikon upped the ante for the same price as a 5DIII. I think they will regroup and have something to show soon but all of the choices suggested don't make sense. The real whole in their lineup is aging middle with the 60D and 7D now 3 years old, but if they go FF they kill of sales of the over priced 5DIII. If they go mega pixels the 1DX line looks silly with an 18MB sensor. the 7D got a firmware face lift. What could they do with the 70D? slightly better sensor? Tweak the focus? big deal. If you were saving for a FF at $2,000 save a bit more the 5DIII will probably drop in price before Christmas. Maybe $3,000, maybe less. Beach Camera had 200 of them for $2,800 last week. Something is wrong somewhere or sales are really strong on the 7D and 60D. 3 years is a record for not refreshing a line. Especially their advanced amateur line. Like I said, I think Nikon really caught them with their pants down.
Maybe on the 5D3, yes. But amateurs really aren't the big buyers of the 5D3 and D800, so I'm going with more of an entry-level type camera to be announced, maybe.
What about the 1DX? When I'm at a football game and all the Nikon users are packing their bags and I'm still clicking off at 1/2000s, the "Canon Camp" really whipped the sh*t out of Nikon on that one. The 1DX is better than any Nikon camera, past or present, period. Maybe not completely for portrait/landscape, but who cares? When you can get that much detail out of an 18 MP sensor, it really doesn't matter. Nikon has absolutely no match at all, with any camera, to match the 1DX's ISO, detail, and AF performance. Yes, the D800 maybe is better than the 5D3, but the 1DX is better than every Nikon camera, period. If you don't believe this, please rent one and go shoot a night game or do some portrait work with it. In my book, Canon wins over all Nikon cameras with their 1DX. Why does that not count for anything, but the D800 vs. 5D3 bullshit still rages on? What about 1DX whipping everything?
