All of the SampleTank instruments are $29 right now...
I'm probably the only one on the planet that doesn't have the full version of SampleTank (I have all the other synths + all the libraries). I don't know if it's worth $29 just to be eligible for the for ST3 upgrade of which I have most of what ST3 is offering........not sure if the all these costs is worth to just get 64bit? (or just go with jbridge and be done with it). 
Also noticed that Miroslav CE (the smaller version) is going for $79.

If I remember correctly, any of the ST products will qualify you for the upgrade...
But I think there will be "tiers" i.e...if you own one $XX, if you own 2 $XX, 3 $XX, etc...
Who knows...at this point, with Komplete, I'm good to go...if I buy anything, it will be the upgrade to Ultimate
at the next half off sale....unless I get ST3 for $29...that would be worth it just to get 64 bit...
IK needs to think about selling "Just the Interface" for dirt cheap, that will still use the old samples...
and THEN if you want the NEW Samples pay $xx....that would be the SMART thing to do....which is why they
won't do it....
