So more than one third of all 360 owners already have the game. It will follow the trend of movie trilogies though with each sequel opening better but having worse legs than the previous version.

Depends what trilogy you speak of. Halo 2 already beat Halo 1, so the only trilogies it can follow are either LOTR/Bourne (they made more money with every installment) or the Matrix trilogy (1st was a hit, 2nd one smashed the record, 3rd not so much). I think it'll be in the LOTR/Bourne camp, beating Halo 2 sales and becoming the best sold of the series. It's already sold phenomenally, and it's heading into a holiday season soon.
