Some ideals of specs out there
I've read some various things around the web about the next incarnation of the 1Ds line. Some stuff is from conversations I've had as well.
proc: Dual DIGIC V 16bit?
FPS (Still): 5-7
FPS: (Movie): Variable, 1-120fps.
AF: A new 45 point system
I'm not sure Canon cares much about WiFi and GPS in camera bodies. I wouldn't hate having wifi, I might use it. I have no clue why I'd want GPS in a camera though, Google Earth applications aside!
I'll be weighing closer to its release. I have it penciled for launch in the first half of 2010.
