The only upside I can see
So you might need glasses then. Say what you want about EA, but there is no denying that they make some of the best games on the market, leaps and bounds over anything Lucas Arts ever published.
So there's one: the increased quality of the potential Star Wars games.
Additionally, EA is a fiscally sound company, They wont start a project, run out of money, wait a few years, get some more money, file for bankruptcy, and drop their product, making it all for naught.
So there's two: the increased probability of a potential Star Wars game actually being released.
Finally, EA has very good hiring practices when it comes to its design-level employees, the types of people who have a near fanatical devotion to their product.
So there's three: the people making the potential Star Wars games will actually care about their product, something Lucas Arts seemed to know nothing about.
