You are correct on both parts Cuk...
Haste will scale better at a super high ilvl, but it has to be to a point where you have just about cleared 13/13 heroic and have everything upgraded so then the question becomes "do i really need to boost dps by 10-15k since everything is down?" Also haste is good for Bear-Catting situations. I have noticed a lot of the end-game guilds have their cat druids doing some bear-cat sharing so they have been stacking more and more haste, you will even see a lot of cats now with crit/haste as well.
But isn't it great being so versatile!!!
As to the PTR question, as far as I know, Cute hasn't had a chance to check out the PTR and it really hasn't been a huge topic of discussion....yet. I am glad you brought it up, it is something that should be on the horizon.
