During Sony's conference at E3 tonight, a GTAV console bundle exclusively for the PS3 was announced. The bundle contains a 500GB PS3 console, a copy of GTAV, a GTAV branded headset with a dedicated GTA sound scheme, and 30 days of PlayStation Plus. This package will be available on the same day the game is released, September 17th, and will cost $ 299 in the US. We'll let you know if any further details come through such as international availability and pricing.
We're not sure how many people are still in the market for a current-gen console, especially with the PS4 and Xbox One releases imminent, and $ 299 does seem a lot for an old console, but nevertheless this will be available for those who want it.
