oh boy alot of hopes and dreams riding on the 7D2
better stock up on tissues people cause there will be plenty of tears...
maybe so. it looks like we can expect a nice feature list, but as for the sensor and native IQ I personally expect only a stop or so of improvement, in native ISO performance. As for fps, I personally don't think Canon would allow the 7D2 to match the 1DX in fps, but 10 is plausible, to be sure.
oh, and for those speculating on the price, Canon did say (if memory serves) that it would be a mid-range body or some similar expression. do the math: half way between rebel and 1DX comes in above the 6D... So it does look like Canon will be pushing the crop envelope.
As for the sensor, lets assume "new process". The 7D2 implimentation will be at the bleeding edge, i.e. technology at its infancy. Sure, a stop of improvement is plausible, over the 7D, perhaps even with an increase in pixel count, but it will still be demonstrably inferior to the 5D3 and 1DX in terms of ISO and noise. Where is the evidence to the contrary? It will be due to mfg or imposed limitations because Canon isn't going to let a crop body outrun a current FF body in the area of DR, noise, and ISO. just an opinion of course. They have 1DX and 5D3 revenue to protect, after all and I don't think these bodies will get refreshed until 2015 at the soonest. I mean I hope a 5D4 comes next year, but that really seems unlikely, as in ridiculously implausible.
So on the "good" side I'd say we can expect the 7D2 to produce slightly better IQ in distance limited situations, compared to a cropped 5D3, due to "more pixels on the duck". This will restore the credibility of the crop body for budget birders and for the 2nd body. It will have an awesome jpg engine. On the "tears" side I think those expecting the 7D2 IQ/Noise/ISO performace to rival that of the 5D3 will be shedding the most tears. initially, the press release will make it sound that good, but when folks discover that the improvement lies in the jpg engine and not native RAW performance, they will be dissapointed.
on edit: what isn't included in the avove is market pressure to lead in the crop space. I don't know how that will influence the 7D2, but it will be really fascinating to see if we have a show much like the 5D3/D800
