According to Space.com, the final selection has been made for the next DISCOVERY mission.
It will be the GRAIL lunar gravity mapping mission. Space.com article Edit: Just noticed that Norm Hartnett posted an official link earlier on the KAGUYA topic: NASA |

The giant impacts did not create the maria. They created the big craters (basins) which contain some of the maria. The maria, the lava flows, are anywhere from 400 to 2000 million years later than the impacts, as shown by sample dating. Since GRAIL's linear features do not follow the pattern of big impact basins either concentrically or radially, they are most likely not related to the impacts.
