I don't know what will be put in the new T4i to distinguish itself from the previous T3i.
A new sensor at higher resolution? I kinda doubt it. If not, what else?
I don't want any more pixels... should have the new Digic V processor for much better handling of ISO.
I really hope they have video autofocus too... the 1DX doesn't seem to have it, but Nikon has had it since the D7000 and packed it with their D31000 and D5100.
