Microsoft: GTA IV has 40 per cent attach rate with new consoles

Microsoft has said that during the first week on sale, 40 per cent of new Xbox 360's were sold with a copy of Rockstar's Grand Theft Auto IV.

The news comes days after Microsoft revealed other significant sales figures claiming 60 per cent of software sales were of the Xbox 360 version, and that the spike pushed hardware sales by 54 per cent.

"The game is attaching well to new consoles, roughly 40 per cent of 360s going out the door had a copy of GTA IV going with them," said a spokesperson on the Major Nelson podcast.

Chart Track data in the UK shows that 514,000 Xbox 360 copies of Grand Theft Auto IV were sold in its first week, while 413,000 copies sold were of the PlayStation 3 SKU.
