Huh. How about that.

So, it's early days on the PTR; thus, all things are subject to change. Buuuut ... I was curious about whether anyone had done any 3.3 Simcrafting, taking into account the haste changes.

Elitist Jerks, naturally, came through. The PP values of the current build, using 3.2.2 BiS T9 gear, and with 2/2 IST etc. etc., are:
Spellpower: 1 (Always)
Hit: 1.42 (No surprises here. Hit's always what you want)
Crit: 0.84 (Fairly consistent, really. It just naturally goes up as gear improves)
Spirit: 0.56 (Very consistent with the buffs to spirit. I guessed this precise number before I even saw it. For me, it would sit at 0.5 exactly because I don't run with 2/2 IST -- IST gives it a little extra push; just over 10%, as you see)
Int: 0.24
Haste: 1.31

Haste is better than Spellpower.

But don't all start gemming for it just yet. Early days, folks, early days. If these numbers do make it to Live, I would recommend exercising caution -- consider full Reckless gems rather than switching everything to Quick King's Amber. Scaling relies on all the stats available. The values above are from a full complement of BiS tier 9, gemmed optimally for 3.2.2 stats. In other words, all the slots apart from two would be gemmed pure spellpower. If you sink >200 spellpower and turn it all into haste, and then run the 20,000 Simcraft iterations again, you're going to get a much smaller gap between Spellpower and Haste: you'll speed up, but each thing you do will be doing less damage.

When MMO-Champion starts giving us enough data to build a Tier 10 BiS list, we'll be able to see the theoretical scaling values of a set with full Quick King's Amber versus one with full Reckless Ametrine or Runed Cardinal Ruby. My intuition tells me that Reckless will be the way to go, but time will tell.
