I just thought I'd post up a few of the latest pictures they've shown so far for the shader 3.0 changes, so apologies if you are already following this in the dev thread, but they are just too awesome to not repeat.
As for release dates, it sounds like they have probably missed the next patch since they are not on the test server yet, but will probably get hotfixed in (status is complete but there is something that needs changing to improve performance).
