We don’t have the stats for the US but, ChartTrack published the numbers of sales and stated that Grand Theft Auto IV has just become the best selling title ever released in the UK on a 24 hour basis.

The game sold 609,000 copies, over 100,000 more than the previous record holder, another title in the GTA franchise: San Andreas (with 24 hour sales of 501,000). Also, ChartTrack said that Xbox 360 copies of the game outsold the PS3 ones by 61,000 (in other words, the Xbox 360 version got 55% of the sales, while the PS3 only got 45%).

So, as it was expected, Grand Theft Auto IV is bringing the big bucks to the developers.
