If that ISO rumor is right then Canon will be kicking themselves. I'm not buying this rumor. Can't imagine the lower lever camera (T4i) having better ISO performance than their higher counterpart.
Good grief, it's about usable iso settings, what good would 6d-like settings do if all you get is noise? If you are so desperate for noisy pictures, just shoot @iso12800 on crop and underexpose -3ev...
... I'd be happy if Canon would end the marketing race in both the mp and iso setting category but just release sensors with more dr and 2 stops better iso than now.
No need for the "Good grief"
I don't recall anybody saying they were desperate for noisy pictures. Not sure where you conjured up that idea from.
I clearly said they they will need to improve IQ or sales will drop. If you understood you would realize that the higher unusable max ISO rating they give will mean a higher usable ISO which means a cleaner low ISO. That is the way it works. Anytime they clean up the low end it will give them the ability to go higher. If they can go higher they will definitely use that number to boost sales. I never shoot above ISO 1600 now because of IQ and very seldom shoot above ISO 500. It would be very nice to have good clean pictures in the 1600- 3200 range for very low light wildlife shooting and super clean shots below that. Sorry if you got so touchy because I am not buying the rumor you posted. It's just rumor talk. Take a chill pill, relax and have fun.
Keep in mind high mp and ISO ratings sell cameras and that is all any of these companies want, To sell products!
