Are you saying they might launch later just to make sure they have best specs and not increase any cost?
---> No. I'm saying why would they bother with the extra year of R&D costs plus potential loss of sales only to make the same mistake next generation? It makes absolutely no sense. Xbox has been here for 3 generations now. Each one they've had the superior console. At best, the ps3 and 360 were a tie. Ps3 was theoretically more powerful but 3rd party games ran worse most of the generation. One X and og xbox are quite above their respective PlayStation comrades. Xbox having the weaker hardware is the exception, not the rule.
