A new Gamma World. Luckily, this is scheduled to come out later this year--with counters which is almost as good as pre-painted minis with stat cards.
A hardcover Omega World. Softcover would be okay. Since they can't do it d20 anymore I guess it would have to be OGL, which would be fine with me. Prepainted minis with stat cards would be great.
That Pathfinder Basic sounds pretty great, too; especially if it had prepainted minis with stat cards. Yes, there's a trend there. And, Pathfinder Basic sounds like the RPG that I could use with my existing collection of D&D minis.
Continuing the theme, Savage Worlds Minis. Generic stat cards that I could use with existing minis would be good, too.
I'll add the calls for a Dungeon Magazine archive CD or DVD. I might never use it, but I would like to have it.
