I have to admit I'm not completely current on what is in the funnel but not yet released. The nice thing about the 3808 compared to other comparably priced receivers is that it allows firmware updates through the built-in ethernet connection. This in itself provides some future-proofing, as they've already released a couple of firmware updates as well as feature additions since I purchased the 3808 a year ago.
Nothing will completely safeguard you against future changes, but I think the 3808 still looks like a fairly safe bet.
Others here can probably comment more specifically about what is in the receiver pipeline but not yet released.
