Now's a good time to remind everyone that these patch notes are not in any way, shape or form complete, and that there will almost certainly be more changes. We've already seen posts from Ghostcrawler indicating that a lot more than this was in the works, so we can consider these changes just preliminary.
So why just roll these two out for warriors? Both are good changes, it's true, but when some classes are seeing major overhauls these look rather paltry. What's going on?
It seems that Arms is a major focus for the dev team for 3.1, for one thing. It makes sense that they might want to roll those changes out more slowly, especially if they're more major changes to the spec than we might otherwise expect. Changing arms without buffing fury accidentally has been stated to be a big priority to them so far so we'll see how that shakes out.
In addition, they're still discussing how to make the new stance system work. Since they haven't decided how that's going to work, it's not surprising that we don't see it rolled out on this patch.
For warriors this is a very preliminary patch, all told. Sunder hasn't been changed, the changes to rage generation through shields don't seem to be there (I didn't see them under the priest notes either) so I'm fairly sure we're going to see a lot more for warriors when all is said and done here. The PTR is dropping in stages this time, we have to keep that in mind.
Edited to Add: MMO-Champion has posted some undocumented changes to warriors.
- Wrecking Crew (Tier 10) now states that it no longer stacks with enrage.
- Titan's Grip (Tier 11) now reduces physical damage you deal by 10%.
- Sunder Armor now reduces target's armor by 4% per application. Stacks up to 5. (Previously reduced armor by a set amount)
