I know that right now they are a little sparse in the types of accommodations that they are able to offer because there will only be certain types of rooms available in the main bldg. Also, it depends on how their schedule goes in getting the rooms completed in the main bldg. I don't think they are going to offer them to the general public by then, though, because the rooms have been booked up since they opened it up to DVC members. If you are looking for that type of room accommodation you would likely do a lot better price-wise through a DVC member by renting their pts. Disney charges an arm and a leg for the 1 and 2 BR accommodations - you can get them for hundreds less (depending on how long you are staying) through a DVC member.
Once they have the separate DVC bldg. built there, the availability will be a lot better for the general public... but for right now things are booked solid for the DVC rooms in the main bldg. by DVC members.
