I read a new post on which-canon-camera which says that Impress Magazine predict the release to be at 85% probability. Impress being based in Tokyo perhaps have a higher chance than most of getting it right.
That sounds reasonable, but I think the question is not if
they will be a Mark II, but when
it will be released. I don't think it will be too soon though, since they just released that big firmware upgrade half a year ago.
Lets hope the upgrade extends beyond fps and megapixels as that is all becoming boring.
Hm, what else can be improved on this camera than performance? Wifi, OK I don't care, but please - no flipscreen.
