Yes, but many D&D players (including me) don't have a lot of those books. The Monster Vault should contain all of the iconic monsters and they should all be usable.
Drow are included, but there are not enough for them to be usable in any way other than a single encounter.
Wait, you claim the drow get no love, yet are in every Monster book and the guides for FR and Eberron?
And then complain you don't own all those books?!?!?!
Your expectations are a little....out there. As suggested above, a DDI subscription would get you all the stat blck info as well as teh Dungeon and Dragon articles.
