There won't be, just ugly little clone babies. XD
You and I are probably right. In some ways, I can sort of understand why they won't do beast race children, since that would require a lot more work than they're willing to do for the (in the case of Skyrim) "less important races" (no offense intended towards anyone), but it's absolutely ridiculous that they don't even do children for the elf races. I mean, how hard could it be to just change up the ears, eyes and skin tone (and in the case of orcs, give them different noses and add the teeth) and come up with elven children? As a matter of fact, doing beast children probably wouldn't be so difficult at their end, either, since they can do more with animations than modders can, which I think is the real killer from what I've read.
But like I said, it probably just isn't important enough to them for this game, since vast majority of the characters in-game are Nords, and they probably figure that the vast majority of players play as Nords as well, since they're the native race. Of course, Nords got screwed over with the orange glowy eyes as well, despite the promotional image of the "Nord Vampire Dovahkiin" with the "grand glowing orange eyes" (which they don't even get to have).
