I have 5 U-he vst3i and vst3 plugins in linux reaper at this time,
so I doubt moving away from vst2 means a hindrance to
the creation of more native linux plugins. Coders can
choose what they make, and what they use to make it.
Are there some specific issues or products you're concered with?
Cheers
