Just looking at how badly the PS3 is demolishing the 360 each week, I'd say it was a pretty good comeback. Easily the biggest gaming related comeback in history.
I know the PS3 isn't going to pass the Wii anytime soon, but I'd still call it a comeback. The PS3 couldn't even manage 100k sales before the price drop and developers were threatening to stop supporting it (Activision and I think one other) and now even Valve admitted they should have worked more on the PS3.
Nobody can say this isn't a comeback of sorts. Well actually I wouldn't call it a comeback, maybe a turnaround or turn of events.
