Honestly Canon needs to get this thing out there very soon with the D600 and Sony A99 around the corner. Granted at $2800 the A99 is going to be more costly than both of them, but it's specs are ridiculous:
24.3 Mpx Full frame CMOS Exmor sensor
New Bionz imaging engine

ISO 100 up to 25.600
50 ISO extended (with lower dynamic range)
102 AF point AF (11 cross).
Dual Phase detection system (with AF phase pixels on sensor)
30 sec and 1/8000 maximum shutter speed
Time Lag 0.05 sec.
Shutter life guarantee of 200,000 cycles
2.360k OLED electronic viewfinder
3″921k LCD with same tilting system of the A77

New accessories to be released with the a99: battery grip, flash, remote control, microphone etc.
Very light, weather sealed magnesium alloy body.With 730 g this is the lightest FF body on market!
Price unconfirmed yet but should be at around 2800 Dollars.
I'm definitely interested in this thing, I think this is going to seriously eat into 5D3 sales.
