Looking over my list of libraries* it seems that ST3 will most likely be redundant or at minimum unnecessary since I have not opened it up since I went 64bit.
(I wonder if I'll be proved wrong)
*
Komplete 8, Kirk Hunter Strings, All the guitar libraries (Waves Factory, Real Guitar, Orange Tree, AAS etc.), Soundiron Venus & Mars
EWQL - Ra, Gypsy, FabFour, Ministry of Rock, Voices of Passion, Symphonic Choirs & Symphonic Orchestra
So end of my rant about ST3 taking a lifetime to bring to market.
Now if they give it to me for free (the player) as a customer loyalty gesture and let me choose any add on libraries at a later date I will not turn it down.
