It would appear that Bioware is pretty confident with their development in Star Wars: The Old Republic, as their co-founder has recently detailed looking into new avenues for online gaming. Dr. Greg Zeschuk explained at the Develop Conference in Brighton about how Bioware has really learned a lot from their experience in the gaming industry. They're also still learning today.
This probably just means that Bioware is looking to find new ways of fitting their conversation wheel into various online games, but who knows. As a company that always seems to have big titles in development, it's not hard to imagine there's a lot of trial and error that goes on behind closed doors. It's at least good to know that SWTOR isn't the only foray into massively online games Bioware is considering.
