I don't think spears are about TESIII. Swords, axes and hammers have been in almost every single fantasy RPG out there, having spears adds a less common weapon option and also an entirely new weapon type to the game, which will make it a lot fresher.
This.
Although, to be honest, spears were pretty much the most common weapon in the real world when it comes to warfare (prior to mass-produced firearms, essentially) and for a game like TES that takes itself quite seriously, for spears not to be in at the vanilla stage of things is a bit of a misstep IMO.
