All the rumors sites are lighting up like Christmas trees. New 50Mpx cameras from the big three are just around the corner. The big three being Canon, Nikon and Sony.
I know Canon has been working on a 50Mpx camera for many moons now. They were having issues with battery life last I remember. You know Canon, if the battery doesn’t last two weeks it’s not perfect enough. I believe this mentality has likely contributed to Canon “falling behind” in the recent years. Sony seems to takes the shotgun approach spamming the market with everything to see what sticks (they’ll fix it in the next version) and Nikon builds these little engineering marvels that are truly amazing in their own right.
