So, will Canon actually try to compete with Nikon this time (in the $1000 range) or will they pull another "6D move" and demand $1500 for a slightly updated 7D with wifi?
I think for Canon to keep my vote they need to address the following with this new DSLR;
1. Price, the Nikon D7100 and D5200 are proving to be great cameras in the $1000 range (give or take a $100 or 2). Also the Panasonic GH3 is another great camera to be had int his range.
2. Noise patterns, I'm aware APS-C won't reach the same low-light performance as "Full Frame" but everyone else's is getting acceptably close, I expect usable ISO 3200 this time.
3. Clean HDMI out, Canon is now the only one without it and they've proved that they are holding it back with firmware so they really shouldn't have an excuse to omit it.
4. Video Moire, it's low on most of the new cameras and this is where the 6D and T4i are failing so Canon needs
another win to equal the others in this department with a camera other than the $3000 5D3.
I expect this "70D" to be a 7D with wifi and a slightly lower build quality with a reduction of minor features (1/4000th shutter, 1/200th flash sync, 5fps, SD card slot, no PC sync and no headphone jack) but I hope they took steps (no line-skipping) to make this the best APS-C video DSLR. That would leave the 7D2 to try and be the best APS-C sport/wildlife camera (hopefully with a built-in 2x crop mode like the D7100 but with 10fps and all cross-type AF points

). The 6D's greatest weakness (video moire) could be the 70D's greatest strength, since we know it won't be low-light performance or fast photos.
