I'm not saying it is, and I personally doubt it...but I just wanted to be the first to notice if it is. Over at Major Nelson's blog...there's a new post about a "a never before announced major franchise on Xbox Live Arcade." Could it be? Our beloved Marathon? If Major Nelson is posting it, it's most likely a Microsoft property. And we all know that Bungie was interested in doing a XBLA title.

Even if it isn't Marathon though, I'm excited by all this jazz. Getting some of the cool stuff from E3 (like the Lost Planet demo) was one of the coolest things to happen in a long time.
