The rumor didn't say the same sensor, just Olog-hai there preemptively complaining.
well we are not all braindead fantasy freaks who believe in miracles... gaffer gamgee.
my last 5 predictions were dead on.. i would be glad to be wrong this time... but i doubt it.
the first APS-C camera from canon to have a new sensor design will be the 7D MK2.
That could come in handy as a probable 2014 release. New sensor design then would be the base for upcoming body upgrades like the 5DIII which could be replaced by 2015 and at least 1D type body maybe the following year.
