I can't speak for anyone else, but my Xsan 3 info is all sourced from the Apple Developer Forums, which are under NDA. So I can't share what I know without breaking that agreement. Mountain Lion will be released in the next few weeks, be patient. If you can't wait, access to those Dev forums comes with the $99 Mac Developer annual membership.
I'd say it already is awesome. Arguably the most advanced and highest performing clustered filesystem on the market (StorNext) is included for free with $29 Lion and will be even cheaper in $19 Mountain Lion. Yeah, there's all the complexity that goes along with actually using it, but for as much as everyone whines about how Apple is dumbing everything down, you'd think we would appreciate this one aspect of their products that is decidedly very, very PRO.
I realize Xsan has fallen out of favor with the video world, but that is only because the video world no longer needs Xsan's capabilities to share storage. Ethernet is enough now. That doesn't make Xsan any less impressive or awesome a thing.
We're still waiting for new documentation from Apple, but it is apparently based on StorNext 4.2.X which has larger inodes and can accommodate Native Extended Attributes with StorNext MDCs and Xsan clients (previously impossible). I'm afraid I'm not aware of any other new features, I'm looking forward to the release of the Xsan 3.0 Admin Guide.
I am not nor was at any time asking you to give up your honor with your NDAs. I am more diasspointed with the lack of new features. While it is a filesystem I was looking for some real shit - maybe PCs without StoreNext, HSM, or any of a dozen things people have been asking for.

I'd expect their licensing agreement with Quantum to forbid platforms other than OS X. HSM is pretty enterprise-y, and Apple has made it abundantly clear they have no interest in the enterprise. I'm honestly surprised they still bother with Xsan at all, given that ambivalence to the enterprise market. Yet they give it away, go figure.
Distributed LAN Client support sure would be nice though.

There may be stealth components to the update which could be useful down the line. But particularly given Apple's lack of concern for pro hardware, better support for mixed OS SANs is a huge deal. For us being able to use Native EA is worth considering going to Mountain Lion.

While the concept of Xsan at such a price is awesome in itself are we to believe that the coming update will be awesome in that it addresses more than stability and bugs? Playing around with the golden master it doesn't seem so.
