I pre-ordered Halo 3: ODST and I got my code for unlocking Sergeant Johnson, but I never redeemed the token and was going to do it sometime in the future, but now i realize it says on the back of the card that its only valid to 1/31/10. Is there any chance those nice people at Bungie/Microsoft extended the deadline to redeem him? If not is there any way I could still unlock him using the code somewhere else?
