@dorbin: I think the gap will get back to several million as soon as Sony cuts the PS3 price (probably in august), especially if they announce Gran Turismo 5 at the same time (or announce a PS3 slim).
I think the gap could be back to zero as soon as the end of 2010 since by that time, PS3 will be much cheaper and system sellers like GT5 or GoW 3, or the exclusive FF13 VS will be out.
Still, I think the 360 will easily reach 40 million too...
