This is a topic that came up on a thread called "Thoughts on Archery," but I thought it deserved it's own thread and poll because of the importance of the topic!
If it is true that ammo will be infinite for archery I believe it makes archery less effective and less true to the Elder Scrolls experiences of the past.
In PvP it is a serious issue because there is a big difference in having your archers being able to use infinite ammo or running out of arrows and having to charge in like the rest of the ground forces.
Personally, I think that arrows should be able to be crafted and modified by enchanters (albeit only by certain special arrow enchanting spells).
Using ammo for archery is a great way to enhance and limit the effectiveness of archery at the same time. Ex) Let's say you are an archer with 10 Daedric arrows, you could use your ammo to do the most damage and then join the melee fray. I think limited ammo will encourage the archers to join the melee fray once in a while and not stay a purely ranged character.
Thoughts?
