The official release of Vienna Hybrid Reverb should take place before the end of May. Tutorial videos and demos are already in the make, too.
Hybrid Reverb will be a new addition to the Vienna Suite plugin bundle, and if I'm not mistaken, existing owners of a Vienna Suite license will get it for free (... we will have to wait for the official announcement to see if this initial idea survived the considerations of our marketing department, though ;-) ... ).
