I hope they have horses. I like horses, and so does M'aiq.
If they are in, they most definitely will be improved. Oblivion's horses were so....

Red Dead Redemption was awesome here.
If they have horses, I very much think they wouldn't be stupid enough not to include horse combat. It would ruin the "horse experience"
So I better hope we will have horse combat for that reason.
