There is no new OTB because the developers dont feel like/have the time/the desire/the will to update it. Same goes for the server. There are not many developers on the TFS project and you must remember these people have lives outside of the OT community.
People like
@Mark and
@Dalkon do all they can but you must realize that they are people, and just like the rest of use, have things to do and cant be hooked developing the server.
If you want it then wait for it. If you dont want to wait for it do it yourself and help out with the server you use.
