but its still fake... the Y button is yellow, and there is no A option for accept... still nice though.
They just took screens from the teaser/trailer and put them with a blue tint, a la Halo 2's menu. The fonts look uneven, the 'upgrade' screen is a pretty good giveaway; because Bungie has actually started showing a lot of info on the weapons, etc, and those are models from a completely different game, that don't even fit Halo's style. The initial fake(Shown directly above) was much more convincing, but ultimately proven to be a fake. As for the "multypayer" menu; that wasn't completely wrong, with the new microtransactions, M$ is looking to set up a new system in which you win by quickly using Live Points to purchase as many minor add-ons as possible. The more you pay from a credit card or points card, the higher your multiplier. So, whichever team pays the most, get's a giant Puma at the end, and it falls on top of the other team, playing loud Mariachi music. Thus, the highest "multipay" team wins. I'm sorry, but I was getting bored, and the RvB reference was begging me.
I personally like the picture madspar posted even if it is a fake. I have yet to see an Xbox 360 game with the option to press the 'Y' button to bring up your friends. Also they don't neccessarily need to put 'A' for Accept and 'B' for Back, but I'm sure they will anyway.
