21MP APS C Fair enough for a APS-C sensor
ISO 100-25600 (L: 50, H1 51200, H2 102400) this is a reasonable ISO for a 1DX intended backup camera
Video ‘stills burst’ mode 30/60 fpsI believe the strong point of 7D2 will be video.... if will be capable to shoot 1080P at 60fps and 720P at 90 or 120fps, than this feature will be a real improvement
Full HD video with manual controlexpected....
Single CF Card SlotI believe this will be the biggest disappointment of the rumored camera
19 AF Points all Cross maybe will be a faster AF ( due to the DIGIC 5 processors... I personally prefer a strong 19 AF point instead of a crippled 51 AF.
On chip phase detect pixels for liveview and AF trackingexpected feature
100% ViewfinderNormal in those days
Viewfinder LCD Higher Resolution Than 7Dexpected feature
GPS, WiFigood for distance remote control when shooting wildlife
Alloy body with better weather sealing over 7Dagain...expected feature
The only big question is: how much the IQ will be improved ? i mean high ISO capability and sharpness ( mushy images).
I also believe that with those specs Canon will keep the price under $2000.. maybe at 1899 or 1999 at launch.
