A new trend I've been seeing with Komplete since version 9 is more of an emphasis on new packs and less on new instruments, which I'm not the biggest fan of (especially as someone who likes to sound design a significant portion of stuff). Presets and packs have their place though... so I'm not COMPLETELY against the trend... =P
Getting 50% off the upgrade price from version 11 to 12 significantly softened the blow for me.
Version 12 gave me hopes when new versions of Kontakt & Massive were announced. Kontakt 6 has raised the bar in terms of CPU efficiency (yay for higher track counts without needing new computer hardware... LOLOL). Nothing revolutionary for most musicians, though back end guys who love to script their own instruments will probably LOVE creator's tools (at the expense of backwards compatibility; it's not a surprising move from NI).
The Massive X workflow has been a slight mind-fuck for me (I guess I'm just really used to the original Massive). There's no standalone version as of writing, which is a shame because I like learning new synths outside Cubase (or whatever DAW I'm using at the provided time). There's also even less graphic feedback than the original Massive (e.g. the envelope graphics at the bottom don't move at all), which I think is hilarious. At the end of the day, I don't think Massive X is a complete fail; I just think it got released way too early. Can you imagine what would have happened if it got released on time?!?!?!
