Tony Hawk's HD revamp won't skip PC, Activision has finally announced. A PC version will be available "a few weeks after" the upcoming Xbox Live Arcade version of the game. What you're seeing above is the first PC screenshot of the game.
For the uninitiated, Tony Hawk's Pro Skater HD includes levels from the first two games in the series. The updated game includes a new soundtrack, and will eventually offer levels and gameplay from Pro Skater 3 as DLC.
Here's two new videos of the game in action:
