I would welcome a survey from Steinberg to all NEK users to understand which elements of NEK are actually used.
For me I use everything that gets baked into the DAW when you have the NEK license: VST expression, List Editor, Score Editor, Chord Track and its tools, Hermode tuning, Drum Editor, (and in the upcoming 6.5 release: Instrument (T)rack 2.0).
I’d like to see these simply as part of Nuendo.
The VST instruments that are part of NEK: LoopMash, Beat Designer, Padshop, Retrologue, Halion Sonic SE, Prologue, Spector, Mystic, (and in the upcoming 6.5 release: Groove Agent, construction kits).
I’d happily see those as just an instrument pack, not a functionality extension. If I wanted them I would pay for them.
I see the logic of having all the instruments as a separate purchase, but not the DAW functionality bits.
