Personally, I feel there are too many possible pieces and too few threads to follow, so just about anything predicting further story development amounts to this:
The thread we've been following since 2.3 has finally finished spinning. There's a lot of pieces, a lot of possibilities, but nothing really hinting at further development unless the Warring Triad becomes MSQ relevant. The only things I can say with relative certainty are that it will be setting up 4.0, there will be Garlean involvement, and Ala Mhigo will probably have something to do with it.
