I'm waiting for 650D too.5Dmk2 at 3200 iso with a 50mm f1.4 center focus point you will be fine. upcoming price drops for new or cheaper second hand might be more in line with what you need
One question about XXXD line. If it is a line for photographers-beginners (or amateurs with little money), then why they should require so many megapixles?
Aren't megapixels for studio (or landscape) photographers, who can shoot REALLY well and make money on this?
What is the profit of 18 mp if a person can't shoot well?
Further more, 18mp require really good AF (if one shoots portraits), very good lenses (calibrated in service-centre), micro AF adjustment (which is missing in XXXd) and good patience when pictures are somewhat out of focus.
Am I the only one who sees that xxxd line is not "well balanced" in terms of feautures and target audience?
Most of the time I shoot in clubs, I need clean high iso, accurate AF, excellent background blur => "sports camera" is for me, however, there is not a single canon camera that is targeted for such audience under 1Dx ((
