I'm not sleeping on it, really.
It's just hard to get excited and list unknown games coming from not-confirmed devs, as opposed to known quantities (games announced or proven studios who will 100% soon unveil games like MachineGames).
Kojima Prod is probably making a game for Xbox, but is it going to be at this E3? I doubt it.
Avalanche is maybe making a game for Xbox, but it's even less certain and they don't have the same track record.
Some of my favorite Xbox games came from the Publishing side, so I believe they're making some big moves, but for now we're not sure about any of it.
