These units have been released for not yet a month and there's been internal discussion of upcoming external reviews, all one can say is it is a job for an experienced reviewer and also not a job that takes 10 minutes to do properly.
Watch this space. 
Sure i will do.
For my needing at the moment would be enough a simple video showing basic task like a filter curve tracing, some GUI iteration, maybe a shot inside, just to get a short glimpse about build quality and decide if it's the case to wait for serious reviews and not to go with Rigol right now.
Any hidden owner of this SA is advised ;-)
What attracts me over DSA815 is the superior frequency coverage, 2.1 Ghz means that it comes in handy for L-Band GPS and Inmarsat LNAs & Antennas.
Anyway, if really this instrument is on the market since one month, the complete absence of any sort of photo / video document on the WWW seems quite strange.
