I sent a mail to mixbus about the update. This is the mail that was sent back.

Mixbus v3 is underway but we have not set a release date.
The next update will be 2.3, which is free for all customers and subscribers.
v3 is a free update for our subscribers ( a subscription is $9 per month ). Other customers will receive a promotional update price when v3 launches.
Best Regards,
Ben Loftis
