COD 4 and Warhawk for Haze??

I was thinking about selling these games for a preorder of haze. For some reason, with only these two games, I can never connect to matchmaking, and cant play online with them. I can play online multiplayer with all my other games, but these two for some reason wont play online. I cant play them, so should I sell them on amazon, which will be enough to buy Haze? Haze looks real good, and Im wondering if this is worth it.

Pretty risky doing it for a pre-order.dazman31

Well I might just order the game the day it releases instead of a preorder if it gets good scores, so should I sell these games??
