Interesting that Native Instruments still haven't released Kontakt 6.

Kontakt 5 was released in September 2011. I understand Kontakt 6 is still only in Alpha testing, so it looks like it will still be quite a while before an upgraded version of Kontakt is released.

Accordingly, Komplete 11 will launch with Kontakt 5 bundled in, which all Komplete 10 and 9 users already have. I currently run Komplete 10 Ultimate and use Kontakt 5 as the sound engine for the 'home / entertainment organ' part of my virtual instrument setup. There is not enough in the K11 bundle to get me to upgrade now so I'll be waiting until an edition of Komplete is released which contains Kontakt 6. Hopefully Kontakt 6 will have an expandable (not fixed size) User Interface window to allow the proper use of larger and higher resolution monitors.
