Maybe you're right. Now that I consider 50D, which is 15MP at 6.3fps, so Digic 4 can do at least 18MP at 5.3fps for 60D. Not great, but enough for me.J said:Last times there were sounds of Digic 5 was 7D then 1D4. Canon is getting a lot of mileage out of 4; it must have been quite a solid design.
I'm thinking 60D is more 4; I don't expect the camera to do anything beyond what Canon has already released. 1Ds4 as the first 5 is my guess--a new processor to match a new cutting-edge sensor. Perhaps updated to be programmable even?
