Microsoft pushed back next Xbox reveal because it's not afraid of PS4?

Why would they push back an announcement if there was no pressure? It seems to me if you are comfortable with what you have, you go ahead with the (rumored) original announcement date.

On the other hand, if you feel changes need to be made, then you are forced to delay your announcement.

I would assume they mean no pressure to rush to announce the hardware. I'm not saying the PS4 announcement was premature, but they didn't even have a console to show.

I'm just basing my opinion on the part that said, "saw little competitive pressure from Sony."  If there is no pressure from a competitive standpoint, you just announce your great news and crush them.  The only other thing that makes sense to me is that the rumored announcement date was just wrong.
