The scene looks really great!
I don't have such a big problem with a jump of quality from scene to scene (HD to SD), since it is still way better, than watching the whole GUOT in shoddy SD. But with the new material it's almost seemless.
I think when the official Blu-Ray's come out it will be one of the most important projects, having a "real" as good as possible version of the UT in HD.
Looking foreward to the developments...
