I'm pretty sure we know absolutely which races are in (Human, dwarf, elf, half-elf, half-ling, eladrin, tiefling, dragonborn) from Races & Classes, but do
not know with the same ironclad assurance which classes are in (but still: everyone will be amazed if it's not Fighter, Paladin, Cleric, Warlord, Ranger, Rogue, Warlock, Wizard).
If by "characteristics" you mean Strength, Dexterity, et al: we know that there's a point buy and a method for rolling presented as equal options in the PHB, but not what the precise nature of each is (again, surprises all around if they're not 28 point buy and 4d6 drop lowest to taste).
Hit points: No idea.
Oh, and Ninja (for posting, y'see), apparently. Darn you, Mourn!!!
