It will?People obviously don't care about it now, seeing as how the PS3 keeps lagging behind the X360 in the US; and it'll change very slowly as we move on...
I'd say that Blu-Ray hasn't had a good chance of having an impact anywhere due to the format war. Which was as good a reason as any for Microsoft to fund it. But the format war is pretty much settled, and this will penetrate into the public mind, which, combined with a lowered PS3 price, could very well spell a quite rapid shift.
This time next year, we'll know.
But I don't think EA is wrong in predicting an upswing for the PS3, mostly at the expense of 360 market share, with the Wii still outclassing both the lower volume platforms.
