WotC will only impose price floors if they think that it will increase sales overall. Given that they have much better market research than I do, I will defer to their judgement.
For the record, I don't think they will do anything for RPGs. Local gaming stores aren't really necessary for gaming. I think most people are introduced via friends, and if WotC can establish a decent presence in regular book stores, that will be enough.
However, a much more interesting area is Magic: the Gathering. Local card stores are focal points for Magic, and a lot of the entry level tournaments (Friday Night Magic, etc.) are held at local stores. However, there is a large portion of players who will go to the stores and play in the tournaments, but go home and order their cards from internet retailers.
This is much closer to the classic "free-rider" problem which price floors are designed to combat. If local stores see that no one at tournaments actually buys cards from them, a lot of them are going to wonder if holding tournaments is actually a good idea.
