I don't know about 1.2, but it should come when its perceived as done.
However I know quite a few players who would be keen to check out how the new demigods play. Having them all back in the game, at the same time as the sale bringing in new players, as well as community/matchmaking feautres to get them friending and playing with each other?
1.2 would be icing on the cake.
Just looking good on the Demigod front.
