There are always a number of things people worry about when it comes to a PC game hitting consoles, but from what has been shown off thus far, Diablo III is looking like it will be setting up quite nicely for the PlayStation 3.

This is an area that could've been a deal-breaker for the game if people the developers didn't work it out.
