I seem to recall them saying they used reach's mulitplayer for CEA for two reasons A. They didn't want to divide the community and B. because CE (for xbox) didn't have live support and they didn't want to slap sloppy netcode on it (so they say). But halo 2 had live support...so hopefully that would make a rerelease much smoother. Honestly, I'd just be happy with an live arcade release with live support. Clan support intact etc. we'll see though. Here's to hopin' Halo 4 is solid :) If they waited for the ten year anniversary that would make it a 2014 release.... and by then...if you've stopped playing Halo 4 I don't think you'd start up again.
