Now, the China Rising DLC isnt whats described there, thats clearly the Premium subscription and i've barely followed the BF series since a month into BF3, never even played the Karkand DLC and i'd been looking forward to that since it was known. Im tempted to preorder this, and cancel it if they reneg the offer. Im not sure i'd bother buying it otherwise.
