@BKK2: It's not official but ioi said in one of the pal charts (when AC debuted) that AC for X360 made 135k first week and CoD4 (for X360) 115k in its second week.

So with mentioned eariler Halo 3 and Fifa for PS2 there are at least 17 games that broke 100k first week. The other game I think of are Vegas 2 for X360 (only 1k below AC according to chart track), Fifa 08 for X360 (it's very close to 100k as it can be calculated from chart track news) and PES for PS2.
