I'll not hold my breath on the high ISO performance of the 7D. Canon seem to be fixated with cramming more and more pixels onto the APS-C sensor. The 7D is an 18Mp camera. I'll be very pleasantly surprised if the ISO performance is even on a par with the 40D let alone better. Here's hoping...
Personally I would have preferred them to use the APS-H sensor out of the 1D range. With twin DIGIC IV processors it would have been a camera to truelly fill the gap between the 50D and the 5D mkII or even 1D MkIII.
To my mind Canon seem to be overfilling their portfolio. Choosing a camera is confusing enough as it is. Canon's range of DSLRs overlap on several different fronts and for me not one of them delivers everything that I would wish for. That is until you start looking at the 1D and 1Ds....
