1. Tome of Horrors 4E: if WotC leaves monsters out of the offial rules, we will put them back in (cant say which ones cause we dont have the rules yet). Plus all the classics from the original Tome that you want in your 4E game will be back.
2. Advanced Player's Guide: To be designed in part by industry insider Ari Marmell, if they left classes and races out, we put them back in (Of course, we can't say if bards or druids or barbarians or gnomes or half-orc are or arent in 4th edition, but we know some stuff has been cut, and whatever is missing we will create for you with work by respected designer Ari Marmell.)
