Little Battlers eXperience W!
No, I don't really want that. It'll encourage Level 5 to keep making rubbish.
I'd most like Hearts R & Innocence R. I'd also be down for Exstetra and Labyrinth Cross Blood. The rest, not so much (except Sen no Kiseki, which I fully expect XSEED to get around to in about 10 years time).
edit: Oh, and I'd like NISA to hurry up and announce Neptunia Re;birth.
