a public beta is available as of now.
here's a couple of things i'd like to mention: OS3 is available for the entire Ti series including the snow. we could have easy limited it to the new TI but we didn't for a simple reason. it's really old fashion and not beneficial for anybody (including us). so treat it as a gift
the TI is in for the long run, in other words - there will be updates to the entire series as long as it is technically feasible.
best regards,
marc
ps. our entire support team is on the NAMM. please understand that there might be increased turnaround times for the ticket for the next couple of days.
