Shaders won't be going in with this update. They are still analyzing and tweaking performance.
The update is in fact GU 54, we're calling it Will of a Tyrant - the update is the massive bug stomping. Also in this update, but not necessarily immediately activated on test when it updates later today - Frostfell and the second part of the prelude events leading up to the expansion.
We're planning for this to go to the live servers on Dec 1st, although that date is subject to change.
