That's very kind of you to say :)
I'm hard at work on the new version of USM right now, for G8-8.1 and G9. I am already tinkering with expressions as well and plan to get a lot of G9 expressions out as soon as possible, because the new face rig looks amazing :)
As for poses, I'm finding a lot of improvements in the bends on the new figure, and a few things I'm really not thrilled with, however I'm hoping those issues will be fixable once they launch the official face and body morph packs.
As far as body poses, I'll be working up lots of new stuff for G9, however I'm quickly realizing that it may be some time before G9 is in a state that it's truly "usable" for most people, This happened with G3, then G8, then 8.1. It just takes time to get enough clothes, hair, characters etc. before a new figure starts getting used heavily.
Basically, if I can't reliably create good promo art with the figures, what that tells me is it's a bit early to start pushing out new pose sets. But I'll have plenty of stuff ready to go as soon as the G9 "ecosystem" is ready to render, which hopefully won't be too far away :D
edit:
I have some great ideas I've been wanting to add to the "Showcase" line that also included a lot of male poses, many of these are done on G8, and I plan to produce those for G9 as well :)
