While Zen Studios may be the Pinball aficionados on the PlayStation 3 and Xbox 360, it appears Sony themselves are taking action on the PSP with Pinball Heroes.

The ESRB has leaked news of this new Pinball game, but unlike Zen Pinball and Pinball FX this series will be entirely dependent on Sony's own intellectual property, and each table will be released separately. The ESRB claims that Uncharted, PAIN, High Velocity Bowling and Hot Shots Golf will each get its own table.

The ratings also describes some of the gimmicks of the tables - the Uncharted board will has a crashed airplane and have gold coins for bumpers, while the Hot Shots Golf board will be set up like a miniature putting green, and will include a water hazard to avoid and fairway targets to hit.

Outside of the rating board reveal, we don't know anything else about the series - for all we know Zen Studios are developing these too, but we'll likely hear something about it in a couple of weeks.
