Just received the email from NI saying if you own Komplete 15, that they have introduced lower-priced update paths to Komplete 26 throughout the year, so you can stay current "whenever you're ready."
This makes me more optimistic on this release. Due to the insane abundance of virtual instruments/plugins that are available - and changes the overall music business has endured over the past two or so years - I found no reason to shell out $400 for this update. However, if there are plans to cut that cost throughout the year - there may be a price point that I find the updates to be worthwhile. I'm sure this is based on expected sales data vs actual sales data of the release. Good looking out NI.
