1.3 is going to be primarily gameplay. v1.2's only point is to try to eliminate the last vestiges of memory issues so that we can start evaluating larger maps, more content, etc. in the world.
That sounds great.
I´vent played E: WoM for awhile. Because i played it so much till 1.1 and for 2 weeks after 1.1 came out. I got a little bit bored after that. New gameplay improvements, new content etc. will bring me back. 
And.... *finger crossed* for E: FE
