I wonder. if that's the reason, why 343i didn't announce the final name for the Next Halo game? It kinda makes sense, with all those leaks, but I'm still a little bit sceptical. If those Halo 3/4 ports are happening and are in fact comming with the Halo 2 War Collection, it will be a pretty busy year for 343i and their partners.
I also wonder, when they made that decision? Maybe, when Corrinne Yu and others left 343i and others started to join?
I don't know guys, something about this sounds fishy to me... I want to believe this.
