Yeah I heard about this from my mates in CCG, feel bad I wasn't on to participate (work's a bitch like that).
I heard that near the end 666 messed it up though- they started attacking the Vanu's territory, which in turn basically ended the alliance and gave the TR breathing room to push out again.
I don't know how much truth there is to that, but I wouldn't be too surprised if that's how it went down honestly; 666 is the closest Zerg/Tyranids/Khorne Beserkers/rabid savages-equivalent this game has.
