The good news that Kontakt 2 is fantastic. The GUI and browser is lightyears beyond K1. The built-in library is incredible. The convolution breathes new life into old instruments. And the KSP function made an unedited, unautomated, cut and dry riff of french horns sound real and expressive (http://www.zirconstudios.com/omfg.mp3).
The bad news? They still didn't fix the damn rendering bug! FL has a workaround for it, but for everyone who was still having problems (there have been many threads on this at the EW forum), they're out of luck.
