This is probably getting overlooked due to the new ships announced at GenCon, but I'm pretty excited by what's apparently called "X-Wing Command".
From the shots here (https://twitter.com/teamcovenant/status/500317670131388416/photo/1) it looks like it's some kind of online tool for sharing campaigns, tracking your collection, and building lists.
There are a lot of good list building tools already out there, it will be interesting to see if FFG can improve on those.
