I don't understand why people think the 7d replacement would be full frame.
If canon bought out a FF 22mp, Pro AF, 7-8fps 7dII at the same SRP of the original 7d, who would pay more then double that for a 1dX?
If canon do bring out another highish fps FF camera, it wont be called the 7dII (or the 5dIII for that matter). They might do this, call it something else, end the 7d line and bring the 70d/80d up to fill the gap. but i doubt it.
I think the 7D Mk II needs to be put to bed now. In my view Canon would be mad to bring out the 7D Mk II as sales are still doing well and its not nearly reached its end of life. It doesn't need to be replaced or upgrades right now. Its serving its purpose on the market so Canon wont touch it just now.
The 5D Mrk III or the 5D X (who knows what they will call it) will be cam on the leaked pics. Thats what the majority of people know/think so can we kill the full frame 7D II idea as its a little off the mark.
