It really depends on the life cycles of both the Xbox 360 and PS3.
From this point on, I think that *best case scenario for the PS3*, that the X360 and PS3 sell around similar numbers until one or the other gives up the ghost and moves to the successor.
Obviously, everyone thinks that the X360 would be the first to do such, since it has more outdated technology, and the more likely candidate to be replaced.
So then the question becomes: How much, and how long, could the Playstation 3 sell to overtake the Xbox 360?
IMO, it could get closer than the 7m it is right now, but IMO, I just don't think the Playstation 3 will have enough gas to beat the X360 - Just like the GC didn't have enough gas to beat the Xbox in North America.
I'm going to say, in my opinion, that the Xbox 360 after the price cut, will maintain a decent lead over the Playstation 3 for about 2-3 years to come, then the PS3 will take over when a successor is announced, and then launched.
9-10m gap when everything is said and done.
Back from the dead, I'm afraid.
