This is it. Tomorrow, during an event that will likely set a new benchmark for dubstep and flashing green lights, we'll finally get to see Microsoft's next gaming console. About time, right? Sony announced the PlayStation 4 in February, and now, just a few weeks before E3, we're finally going to see the other major part of the next-next-next generation: the third Xbox. So just what is up with Microsoft's next Entertainment System™? Luke has already compiled a great list of everything that has been rumored so far, but I want to talk a bit about what we'll likely see at the big Seattle event, which starts at 1pm Eastern tomorrow. (We'll be hosting a livestream and covering all of tomorrow's big news right here on Kotaku, of course.) Let's go through the major bullet points. Xbox... something? Tomorrow, the name Durango will go the way of Orbis. RIP Durango and Orbis. Miss you bros. It's okay, though. No matter what Microsoft has decided to call their next machine—Xbox Infinity, Xbox 720, Xboxtaku, whatever—we'll get the hang of it eventually, just like we got the hang of Xbox 360, and Wii, and Wii U. Err. Well, okay, maybe they shouldn't call it Xbox U. We certainly won't hear everything during tomorrow's smoke-and-mirrors show. Don't expect specifics on the price, release date, or launch lineup, for example. But we will most definitely hear the next Xbox's name, whatever that may be. (My guess: Xbox. Just Xbox. If only to screw with people, Apple-style.) Games? Nobody wants games. For quite some time now, Microsoft has positioned their Xbox not just as a gaming console but as an entertainment device. Multiple rumors from all over the Internet have suggested that the next Xbox will be seriously mad if you only use it for games. Microsoft's new device may support cable in some way—we hear it has an HDMI output and input—and it will most definitely be an all-purpose Swiss army knife of a console that lets you watch movies, record TV, stream online videos, and toast waffles. In other words, a bulk of tomorrow's conference will be about the multimedia services that Xbox Next has to offer. With another big Microsoft presser hitting in just three weeks at E3, it's safe to assume that they're saving some of the system's big game announcements until then. That said... Call of Duty: Shoot People: Return of the Shooting ...we will see the next Call of Duty tomorrow. There will be guns. There might even be explosions. Angry men will shoot at things. Bank on it. Expect at least a few minutes of footage from Call of Duty: Ghosts, along with someone talking about how amazing it's going to be on the next Xbox's version of Xbox Live. Maybe we'll hear about some of the cool new things that developers can do with Achievements on the new system. Maybe they'll tell us how to avoid getting called racial slurs by thirteen-year-old boys. Futbol!!! We're also going to see some FIFA. Expect gorgeous graphics and a whole lot of chatter about how the next Xbox will revolutionize the way you can play soccer. (This time, you'll be able to play with other people!) Wild Wild West Do you live in Japan? Sorry! Tomorrow's big event is at 1pm Eastern, which is actually 2am in Japan. Perhaps Microsoft is admitting defeat in the East, where they've never quite been able to sell consoles. My guess: we're not going to see much of a Japanese presence at tomorrow's event, if we see any at all. Unless Square Enix shows up and plays the Luminous Engine trailer, which would make it the funniest event in gaming history. One gimmick to rule them all According to Paul Thurrott, a Windows Super Site writer who first nailed down the May 21 date for the big reveal event, we'll see Microsoft's fancy IllumiRoom technology tomorrow. It's basically a giant projector. This is what it looks like in action: Will this be part of the next Xbox? An accessory? A silly gimmick? I guess we'll see tomorrow. Online what? Tomorrow, after months and years of rumors, we could finally find out the truth: will the next Xbox require an Internet connection for games to work? Well, or we could find out nothing. Microsoft could be annoyingly vague—"Today's gamer is always connected, and this console is for them."—and refuse to answer questions about how any online-only functionality/anti-used-game protection works. Don't expect them to be clear about everything. So, okay. Here's my final, totally unsubstantiated prediction for how the day will go: 2 minutes of introduction, bragging about Xbox 360, introduction to [XBOX NEXT NAME]30 minutes of entertainment features and cable15 minutes of the new Xbox Live15 minutes of random developers talking about how awesome Microsoft is7-8 minutes of Call of Duty7-8 minutes of FIFASURPRISE GUEST APPEARANCE! Could it be Rockstar? Bethesda? BioWare? We'll see a sizzling teaser, and it will be a DURANGO EXCLUSIVE. Everyone will freak out. There will be GIFs everywhere. Reporters will write that it's a real landscape-changer, that Sony should be seriously worried about the next Xbox. And then the game will never come out. Okay. Your turn. What do you expect to see tomorrow?
