Makai Shin Trillion, Neptunia U, Moe Chronicles and perhaps one of the other Nep games all feel like safe bets. Hoping they localize something unexpected from another company, but we'll see.
Neptunia U has already been announced for localization, although we might get a release date for the game today. The only unnannounced Neptunia games are Neptunia VII (PS4) and the two Vita games recently announced (Vs Sega Girls and Blanc Tag Team).
