EA needs to think of this in a positive way. Giving up the Engine will slow down the dev team from making PR2 in the future when shittier games are still coming out, because in the future when the industry is still taking shortcuts and making stupid design decisions just to sell a game for a year, then PR2 would be the most dangerous game to them.
They should really think about it as PR will always be underdog on BF2. Most regular gamers will still avoid playing PR on BF2, but for us

we'll keep on playing.
