I wonder if they've made the tools pretty easy for the devs to spin it out, especially now with all the guys who are self publishing jumping on, it's almost standing out with the ID@Xbox guys that are coming to PC that choose not too.XPA is getting better. Love it.
I wonder if there is experimenting going on with these 'coming to play Anywhere' after launch to try and get best of both worlds with sales on Xbox and steam.
Hopefully they can get the ball rolling with big publishers.
