The Tony Hawk’s Pro Skater HD Facebook page posted a quote from developer Robomodo about the PS3 release of the game.
“We intend to release the PS3 version the last week of August or early September. While the game does have a short period of exclusivity on Xbox 360 from being in Microsoft’s Summer of Arcade, that has nothing to do with the PS3 release date at this point.” They later went on to say that, “We want a bit more time to polish the game and want the PS3 version to be as sharp as possible.” So it seems that they are taking this exclusivity window as a chance to fix the game up before launch.
The game is currently sitting on a 67 with Metacritic where it has more mixed and negative reviews than positive. We will keep you posted if a more concrete release date is given.
