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 |

It allows craters at mid- to high-latitudes to appear circular. Almost all traditional lunar sheet maps from ACIC, USGS etc. used conformal projections (Mercator, conformal conic, polar stereographic) with that special characteristic. Only with the advent of digital mapping have non-conformal (read: shape-distorting) projections like Simple Cylindrical (Equirectangular) or [shudder] Sinusoidal been used to any extent.
