Don't read too much into the term "Dealer stock only". Sometimes, yes it means they are dropping something. More often than not it means they are over stocked and aren't going to make build custom orders until stock is used up. It can also mean that the model is about to change due to the new model year.
When we bought our X20E the website said "Dealer stock only". The X20E was available for at least 3 more years after we bought ours.
