I'd like to see gnomes. Rock, Forest and Deep. +2 INT is nice for wizards. On top of that Rock get CON bonus and the other 2, DEX bonuses. Story wise Rock gnome are the "common" gnome and if you are thinking about crafting, these guys make interesting trinkets. Forest gnomes have more of a feel for mixing with druids. I see a lot of NPC interaction for deep gnomes as well.
