Yup, there's a 2 player section in the rulebook. Works the same way as the original Cthulhu Wars two player rules - 2 factions each. Theoretically, you could also use 3-4 factions each for a mega game.
I imagine the updated rules for the 2-player Cthulhu Wars could also be adapted for Glorantha - although this'd probably be a fan variant.
Actually, that's old. There is no 2 player version of The Gods War. Sandy is fairly adamant about this, and there is no SG planned to make it 2 player.
It was difficult (more than it might seem) to pull off a good 2 player for CW, and b/c of the differences of TGW, it will be harder. Sandy is happy with it being a multiplayer only strategy game experience.
