I know this is pointless but I had a thought, If the 7D2 is as we think i.e looks the same, feels the same, works the same has a few bells and whistles added but..has a 5D3 or similar autofocus, a one or two stop advantage over the current one and is low 20s million pixels, that moves it into 1D4 territory. I have a 1D4 and sold my 7D as it didnt cut it in low light. If the new one, when it rears its head, is as many think it may be, will it replace a good few 1D4's? Id punt for one for sure. Basically a 5D3 that has a crop sensor and shoots faster. And no, I will never get rid of the 4, it will sit alongside it like my 1DS3, a camera so beat up it looks like ive used it for DIY when I lost my big hammer but still works %100 fine.
