Thats up to Bungie. I know the powers-that-be over at CoD towers frown upon KB+M use, and indeed swing the banhammer in response to it, but Bungie may just shrug and say 'dont like it? Buy one or GTFO'. I'd wait to hear their stance on it. Silence equates to the latter statement. Good luck. Interested to see where Bungie stand on this.
