Agree with OP, but you have to remember what kind of complete domination the PS2 had in its market, we won't see anything like that again for a long time.
This thread, for me, kinda falls in with the "who here still believes there'll be a major turnaround this gen?" or what the hell it was called.
Trends are mostly set and only minor shifts and changes will occur from here on out.
What I don't understand is how anyone could ever think that almost all third parties would jump ship and shift all their efforts onto a single platform within only a few years (that kinda happened with the PS1 but, again, that was an entirely different form of market domination).
