There are plenty of other, newer topics in this forum that highly support the likelihood of the third game, even to the point where we know who's making it.
Really?
Free Radical (
http://www.frd.co.uk/) is supposedly making it.
First you claim that it's known who is making it, and then it's supposedly?
They've even announced a "Secret LucasArts Project." And since we have other evidence to support it, it's highly likely.
Could be anything, could be a BF3, could be the KOTOR-based MMO recently announced. And the evidence isn't exactly conclusive.
