Ah, but....
If Microsoft had total faith in the format they would have made the internal drive for the xbox 360 a HD-DVD unit. The fact they've used an external drive shows that they've been hedging their bets to see which format wins out.
Once Blu-Ray has taken control of the HD Market, Microsoft can either swap the external drive for a Blu-Ray unit or build the next 360 with an internal Blu-Ray drive.
