Gamasutra also called in the pros from Massively.com to break down a few of the screens, which seem to suggest a game UI that, unsurprisingly, was taking a lot of its cues from World of Warcraft. Microsoft and Ensemble have yet to comment on the authenticity of the shots, and the sourcing is a little sketchy, but all of the shots are highly evocative of the Halo aesthetic even when they're not canonical, and the sheer volume of concept art and mock-ups suggests they're legit.
On a personal note, I'm not the world's biggest Halo fan, but I think some of this character stuff looks sick as hell. The environments don't really pop, but I like the way some of them extrapolate from the core Halo design. Mostly, though, I'd just really like to see a non-fantasy MMO get a real foothold, and aside from Starcraft, Halo is probably the best sci-fi candidate. It's a shame that this stuff is probably dead in the water, though you can be sure that this won't be the last time Microsoft considers turning its wildly popular FPS into some recurring monthly payments.
