Well, since we can strip our characters down to their underwear I wouldn't hold my breath waiting to be able to create a character under the age of 18...probably 25 to be on the safer side.

Lol. I never thought of that. But I still don't see it, all I'm asking for is a young face, the body model will be the same for everyone anyway

I know about the mods - they're not an answer to everything, especially with a multi-platform title. Certain features need to be included in the core game, otherwise Bethesda could just release the CK and an empty world and wait until the modders build the whole game themselves. Not exactly what I'd expect from a game developer.
Of course, all of this is more "it'd be nice to have it" than "Skyrim is worthless without it". So for now, mods will have to suffice.
