They should have named it the T4i mark II+1
Nope. In 5D to 5D2, the change is quite remarkable (MP, video, 14-bits, etc...). Even 1d to 1d2 to 1d3 to 1d4, they've got nice improvements. They should just named it T4i with new firmware update.
True, but in reality T5i is a T4i with a new name with very very minor updates. Renaming it the T5i will trick many, but IMO it makes more sense just to name it a T4i mark ii "the same camera with a tweak".
Either way, this camera should have had at least a better upgrade....
