Traps & Treachery II is the only thing out there or coming out soon that I really am yammering for.
Otherwise, in a "wish list" sense, Dear Santa I've been good this year and I want some of this stuff:
1. Book of Challenges II
2. A "phone book" of sorts to all as-yet published D20 rules for everything like water combat rules, alternate magic systems, etc... what book to find them in and a very brief run-down of each.
3. More high-level adventures
4. Monster Manual III?
5. D&D basic or kids' edition
