Yeah, yeah.  UAD is AAX 64 bit Windows ready now.  I've got 5 cores of UAD-2 chompin' at the bit and ready to go... finally.
 
Now, when Slate get's their act together.

I'm waiting to demo their new 1073 until Slate's version comes out.  The shootout, including the new '73s from IK and Waves, should be interesting. 
 
Kinda lame of UA to call their new baby a "collection," though.  It's just the one new plug, with the old one thrown in.  And it's just as pricey as their other collections which contain two or three new models each.  Weak, UA.  Weak.
 
Cheers,
