I just think people wanted something to be true that was highly unlikely to be the case from the very start. I genuinely believe that, deep down, all knew this, but were just having a little fun at the expense of the new xbox.
For those that really believed the next xbox would be weak, well, jokes on them? I don't think a lot of people realize what the rumored GPU for Durango will be capable of in a console. We can't use existing pc games using a similar looking GPU as a judge, because that same attempt with the closest pc equivalent to the ps3 and 360 gpus wouldn't have told us we would be seeing games that look like Uncharted 2, Halo 4, Forza 4, GT5, and a whole host of other games. Weaker than the PS4, if that turns out to be the case, does not mean weak, period.
