We would _love_ a GF DVC. The GF is one of our favorite resorts at WDW, and is the only resort at WDW that we would definitely add many points on to stay it regularly. We would be particularly happy if they did a Concierge/Club level option there... hopefully with more rooms than are available at AKV. It would make sense in some ways, as it is the flagship, and it would be great to offer the premium experience.
If they did a DVC at the Poly first, we might add on points. We like it better than the CR and not as much as the GF. We're still waffling about a BLT add on, as we love being on the monorail with small children. It doesn't make financial sense for us to add on this year... and probably not next year, either. (Adoption expenses are considerable!)
Anyway, we didn't find the GF snooty at all. We _love_ the live music in the lobby. We love the concierge food options. We love the view of the lake in the evening. We love the restaurant options. Heck, we even love walking past the soap store when we get off the monorail in the evening. We're not that into their pool, but unless we're staying at the BC, we're probably not staying at a resort for the pool!
I hope the rumors are true, and they're at least sending out feelers to see how much interest there would be in a GF DVC. They will wrap up BLT, VGC, Kidani, and the treehouses before too long, and they'll only have Hawaii in progress. I think they'll announce something else later in the year or next year, assuming the economy shows signs of recovering. Even if the economy isn't really recovering, eventually they'll make another announcement if they make enough sales of current inventory. They have to do something once BLT and/or AKV get close to selling out. Think about it, they must have a new DVC resort at WDW to offer to the public at all times. This is the bread and butter of DVC, this is what lures the majority of buyers to join. I think it is a matter of when, not if, they'll add DVC to the Poly and GF. (Unforunately, I expect the points required will be at least comparable to BLT or VGC, if not even higher.)
I also think that if they're smart (and I do think they have plenty of smart people in their employ), if they ever do build the elusive 5th park, they should plan a new combination DVC and hotel within either walking distance or a short boat ride. Sort of like AKV/AKL, only a little more convenient to the entrance of the park! That would have to be timed to open with or soon after the new park, so that is probably many years off at this point.
