Full BC in a model that costs $300 or less = I purchase...maybe not right away but probably within a couple of months. Contrary to popular belief I don't hate the PS3 and I have said so all along and have also said all along that I am seriously considering getting one. But that would be the point that I would feel compelled to buy in so long as the PS3 continue to look healthy as it does now...a year ago I would have said "not unless something changes"..and it has.
But if I had to pick just one? They must re-introduce full BC or I will not purchase a PS3, plain and simple.
