It has to be H2, that is great news! I absolutely HATED Halo2 for the Xbox, but if it's ported to the PC PROPERLY I would definately give it another chance no doubt. I have played through Halo about 5 times on the PC I just wish Coop was included... even though there are many Halo haters out there they cant deny that Halo was a excellent game. If and when it comes to PC I would hope to see improvements in the game across the board. Multiplayer would be fantastic on PC as well. When the original Halo was ported it took 8 patches to get the game right. If they learned from that port the game should play excellent out of the box. We will see an anouncement at E3 this year for sure.
