I'm with Grim on some sort of summer league.
Sadly, it is very unlikely that the store will run a 40k league this summer if the Planetary Empires product is scheduled for a July release. It takes a lot of time to get the tiles ready to the standard Derek will want them and given the level of interest we had for the WHFantasy version, we are going to need a very large map (LOTS of tiles = lots of time).
We do have the Lucky 13 events going on for the next 6 months and there's always the 1v1 tourney I spoke about.
