Nope, nothing new. Don't think it's a high priority, either. When they bought the land in Hawaii 3 years ago, they were immediately crowing about how many rooms would be involved, the DVC presence and some estimated opening dates.
When the DC land purchase occurred, there were no details, no concept art, no mention of DVC and no groundbreaking / opening estimates.
In fact, Disney paid so little for the land ($11 million) that it's entirely possible they could simply sell it off in a few years without ever building a hotel/timeshare. The prospect of taking a small loss on the project is immaterial--and they could even end up turning a small profit.
It's also worth noting that Jay Rasulo was the public face of the purchase, but he is no longer in charge of Parks & Resorts. If Tom Staggs doesn't have the same vision for a Disney resort in DC, it ain't happening.
