That's troubling. One hopes they are simply swamped but emails and will eventually get around to everyone, but they risk alienating and angering some indies in the process.
It's not that. Well, not as such
I applied in October, went to the ID@London event in December, demoed my game informally to various Xbox folks whilst there. Have had a number of conversations with people in the Xbox team about how my game would use SmartGlass (one of the technologies they keep mentioning along with Kinect, that they keep telling us devs we should be making to help them shift Xboxes). I ended up part of a little community on facebook of other developers who are on or trying to get on ID@Xbox, and have made efforts to actively participate in that, contribute etc.
But what MS really want are teams with a history of shipping titles, that they can rely on to actually come up with the goods. "Independent" studios of 3 or 4 AAA veterans who've now formed their own new venture with that awesome-yet-slightly-too-crazy-for-publishers idea that they've had brewing for the last few years. Not one-man indie devs straight out of college who take a devkit only to 6 months later mumble something about cancelling their project and going back to making Ludum Dare games "for the art". (I'm slightly exaggerating here
)
Thing is, the game I was working on in December, and showed to the Xbox guys; the other indie dev I was working with on that had to get a day job to support his family. And since it was a job in games industry, his employment contract said he couldn't work on his own games during his spare time. So that game fell through and never came to anything. So MS were right not to give us a devkit!
And from a "gamer" perspective, that means a store of higher quality (polish/production values wise) indie games, and consistency in that quality. And if some indie has the latest crazy-shit-hot game blow up on social media, or get a mazillion greenlight votes, they'll probably get approached by MS anyway, so not like you'll be missing out.
But yeah, just whining because "when can I haz my free xbox devkitz?!11" I mean the whole thing makes sense. MS don't owe me anything, and I'm probably being stupid and slightly naive letting myself get towed along by the hope of getting on the program, when really I ought to be out there making a really cool PC game that then gets picked up on by MS, or that I can go to them with and say "look, I haz gaem! Shiny!"
