Whatever would remain of Maxis would just be a hollow shell though, since I imagine especially of the sims team a lot of staff would resign based on principle due to the change of ownership and plenty fired. And they would take a lot of knowledge with them of how to make this very particular kind of game.
And I'd wish them luck trying to get a new sims game to succeed that won't even allow same sex romance. The competition would bury them alive. Let's face it, the sims has no future unless Maxis goes independent, otherwise it will be up to successor games to fill it's shoes.
Now if another big publisher is smart, they'd use the opportunity to gather up plenty of leaving Maxis staff to put to work on making such a successor game and claim the monopoly on such games that EA will now lose.
