As an archery enthusiast, it definitely would make a lot of tactical sense for there to also be recurve and short bows in the game. Guild Wars executed this particularly well, with bows having varying ranges, speeds, and arcs.
They were then made to curve one way, then bent back the other way when strung. Those were the compact bows that steppe horse archers carried.
You mean as they do with recurve bows? It'd be interesting if some of Skyrim's bows had more defined contours to them - all of Oblivion's were rather unimpressive (to me at least), looking like overdecorated flatbows. Morrowind had some short bows as well, although in Skyrim I'm not sure if we'll be seeing a return to the various types.
On one hand, Bethesda seems to have put a lot more effort into shooting mechanics, but on the other it seems that bows have become more of a "special" weapon: rangers are encouraged more than ever, it seems, to have backup weapons. Now that it takes longer to nock arrows, and we won't simply be holding down the S key whilst firing 30 arrows into every enemy we encounter, that'd be the perfect excuse for them
not to give bows the diversity and attention they deserve.
