There’s a good chance of PS3 and Xbox 360 versions of Sin Episodes, according to an interview with Tom Mustaine (Ritual) over at Ain’t it Cool News. A Snippet:

Monki: Is this going to be PC only I’m guessing?
Tom: We’re actually…no. We’re gunna do a 360 version at some point in the future. We haven’t finalized those plans yet so I haven’t really announced it yet. But we will be doing it. We also are hoping to be doing a Playstation 3 version as well.
