I think we're asking the wrong question here. We shouldn't be trying to judge what we expect from MS - we're all shooting in the dark there, honestly. We should instead try to predict the reactions from the posters here, which we really don't need anything for. E.g.
Mcmasters - A++. Will be the greatest show ever since sliced bread. Will use the letters that he seems to consider a word "bruv" frequently.
Andy - B-. He will actually probably comment intelligently about whatever is announced, even though he'll drop off the stream maybe a third of the way through to start his post-show reaction post.
Valliance - B+. They'll show something that looks like hot sex on the X, and especially if that's anthem, that might become his new obsession, to replace his former love, the PS4 exclusive Destiny.
Rollins - Incomplete. Once the show is over, he'll post the details of the sixteen games in development that weren't announced yet or shown, at least eleven of which are Indie Battle Royale shooters.
Bellybama - Will be missed.
Menace - C-. Something will be cringeworthy or worse at the show. You may forget or forgive, but Pepperidge Farms remembers and Menace is a god-damn Mint Milano.
JinCA - B. Something, something, something, something that sounds vaguely nice about MS, something, something, backhanded compliment about MS, something, something, something about how he doesn't really feel like he's getting value from the X, something, something, some negative comment about MS.
hrudey - no grade given, but will probably post a couple hundred words that, when subjected to extreme lexicographic analysis, will boil down basically to "You're all a bunch of tits." Incidentally, I heart tits.
