For top Xbox 360 games this week, via MGC

As of this second, GTAIV is about 500 cards away from H3, and has surpassed it by now (as the servers update every hour).
How big is this? Call of Duty 4 (which has sold almost 6 million copies worldwide) overtook Halo 3 in about 4 weeks. GTAIV did it in about 24 hours.
Mind you, it will take awhile to get the full numbers from MGC (as they can be a good teller of how sales are going), but judging by the UK Leaderboards, I would say that GTAIV is leaning toward 1m units (or so) in Europe for the X360 first week, or more.
Back from the dead, I'm afraid.
