Play.com games boss Gian Luzio has told MCV that GTA IV is already the fatest selling game on PS3, and that the title is also proving to be a system seller.
"This is the biggest ever title for PS3 by a long way - and probably 360 as well," he said. "I've been really blown away by how quickly it's sold on PS3. Sales have gone crazy and have proven to be a real hardware driver already. We've sold out now, but will be getting in more stock as soon as it becomes available.
"We expect to have some stock back in for the day of release on April 29th."
Many UK retailers are now struggling to meet demand for the game. It was reported yesterday that GAME has stopped guaranteeing release date delivery for the title.
