I'd preorder for PS4 and play on either a PS3/PS4 depending on if I'd gone 8th gen by January; but I've already got a preorder for the 360 now and plan to play the beta on my 360, given that most of the people I play console games online with are on 360/XBL exclusively. Edit: turns out you can redeem more than one beta access code (code "gifts" or from multiple unit preorders) on a single B.net username. I'm sure this info's been posted somewhere already, probably in this group even. And I don't know for certain whether it'll be "limit one beta [i]download[/i] per username". But it shows I have two access keys redeemed on my redemption page now. Fellow greedy guardians hoping to beta test on more than one platform, you seem to be covered. Snag those codes while you can.
