I seriously doubt they're going to start adding mandatory commercials, as long as it's something that can just be skipped immediately with a single click of a button, that's fine, but if it's even 15 seconds that you have to watch each half, that would be ridiculous. I definitely don't think they could make enough money off those commercials to make it worth it. I know that the public will pretty much blindly buy the product year after year, but that might be something big enough to piss people off to have them play the previous years game with no ads, instead of the new game.
