All of the reputation rewards are being rolled over in to the new honor system. You'll be able to buy all the same honor and reputation rewards through the use of honor points and marks of honor which are obtained through general PvP and/or the battlegrounds.
The reputations will still exist but will now instead award you with a special title if you obtain exalted status with all three.
