I understand the logic of EA not developing niche games and the worry that they might kill Dirt Rally off. If that's the case though - why did they buy Codemasters in the first place? That's a lot of money for the trademarks.
EA will turn it into a derby arcade racer, probably with destruction of opponents' cars. To appeal to as broad audience as possible.
Then, do you want a new liveries, new pilot, new tracks - $$$.
After two games series will be killed as its not making 1000% return.
Well only then a new studio will be able to create a new rally series :/
