This! This is why I love Sony. The sheer ridiculousness. If you assume it's confirmation that in-game XMB is coming (and I'm sure it is, they wouldn't joke if they weren't at least working on it,) Sony will totally ignore any questions about a release date for the next fw, and will act like the entire event never happened. Then, the next day, they'll officially announce it, still acting like they've completely surprised everyone.
It's like they live in some kind of weird, half-disconnected bubble, wherein the normal rules of reality don't apply, and they're free to just do whatever the hell they please (i.e. paying taggers to advertise PSP, questionably racist advertisements, really really bizarre PS3 ads with a creepy doll and eggs that explode into crows...etc.)
