Halo Wars is going to be large but Halo Three is going to be larger, the search for the Arc will begin, plus we do not know what will really be added in the third addition of Halo. In addition there is a Halo 2 for the PC comming out very soon Title: Halo 2 Vista
Of course Halo Wars and Halo 3 will eventually come on the PC when Microsoft thinks worthy (since it reaches a larger crowed then the 360)
Any other Thoughts on this subject?
