Considering that a split like this has been discussed here for a while, I am just wondering if this is anything more than a rumour circle - somebody read it here, sent the rumour to NL, and then it found its way back here.
Having said that, I would not object to it being true - I would jump on the "22MP, High-ISO, improved AF" camera in an instant.
I do, however, find it rather unlikely that the two cameras would have the same AF system, but....this is just a CR1 rumour after all, so I am not taking it too seriously.
There seems to be a fairly reliable indication that Canon will be offering a video-oriented EOS camera this year, and quite frankly I find it very unlikely that they will be introducing 3 new ones, so "if" there is a split and we get two different successors to the 5D2, one of them would have to be the "video-oriented" one.
So, shat is more likely - a 40+MP camera with decent video and a 22MP one with top-notch video (as this rumour states) OR a 40+MP camera with top-notch video and a 22MP one with decent video? I'm not 100% certain, but I am certain someone can give a good technical explanation on why one case must be more feasible than the other.
