Major Nelson, the face of Xbox Live, has started a countdown on his blog. This countdown is ticking away toward the future, as countdowns do, and when it hits zero, it will be E3. What could he possibly be teasing? We won’t know until June, but there’s a pretty good chance it’ll be Microsoft’s follow-up to the Xbox, which has popped up now and again (and again) in various rumors. Rumors should always be taken with a grain of salt, and Microsoft has never not given us a big E3 reveal that’s worth counting down to, but still, this could be it. I’m feeling good about it — are you?
