A tweet from Battlefield 3 Lead Designer David Goldfarb confirms that Battlefield 3 will NOT be a PC exclusive, confirming DICE's new love for console systems:

@U2RoKKeR it will not be exclusive. We are putting special effort into the pc version, even for us, it's extraordinary.

ED: The slippery slope to disappointment begins... but looking forward to RO2. It's got all the right ingredients !!
