I don't believe they will go in the right direction, they screwed up Halo 1 HD, and I don't believe they will do anything right for the Halo Series. I'm very disappointed in 343i, I was hoping they would bring Halo 2 back to life on PC and then do the patching to allow Halo 2 Anniversary to be cross platform compatible.
But it seems that PC games are just nothing to them, and I happen to be a pc gamer.
I am also an original xbox live veteran, that misses a good online game.
