Methinks Baal will probably be replacing Anubis so they won't need to bring him back. I mean, assuming Anubis didn't take his entire fleet to Earth, there'd be lots of advanced ships and shipyards and bases around for Baal to gobble up. And once he's done that he'll probably start taking pot-shots at the Asgard to gauge their technology and effectiveness.
But, unlike the situation with Apophis, I think it'd be pretty cool for Anubis to come back but in a vastly diminshed role. Kinda like some spectre that floating aimlessly through the universe. Or is semi-corporeal again but too physically weak to amass power again, and he wages some kind of guerilla war against the SGC, using the remnants of his Super Soldier armies to basically try and destroy Earth, the Ancients, the Asgard, the Goa'uld and basically the entire galaxy purely out of spite.
