Tegal Manor, City of Brass, and the Castlr Zagyg Books or boxeds sets, however they are released.
James Mishlers C&C Wilderlands material should be great.
The mysterious boxed sets Mr. Goodman passingly hinted would be released.
Anything adventure oriented from WOTC, Goodman, Necromancer, XRP, Dungeon, etc...
Don't know about the complete books, I'll have to read them to see, since 3E isn't my main system anymore.
The new Star Wars, for me kids at least. I can have fun playing it but I would rather play Traveller.
L5R material.
The Tile Sets and the Dungeon Mastery stuff from Paizo.
More stuff from Fat Dragon Games, Oone, Skeleton Key, et el....
Maybe start buying Dungeon Forge stuff.
Can't think of anything else right now.
