Ah, cool. Yes, it does seem quite likely that the next Obsidian (non PoE-related) project will go turn-based, once they don't feel beholden to following a specific style.
My sense is that given the choice between the two, and without having to keep with any tradition, they'll invariably go with turn-based. Sawyer's made some arguments in favor of RTwP as a form of combat with its own positive qualities, but it's also hard to get away from the sense that the only real reason PoE isn't turn-based is that the IE games weren't. Certainly, that idea has come up very often.
Without those particular shackles, I'd be quite interested in what type of combat they'd go for.
It's actually what the SA thread uses for its OT, heh.
