I feel that I must remind you that Apple no longer provides updates for your 2010 MacPro and hasn't for a number of years. How can you expect Fractal, a much smaller company, to do something that a much larger company won't?
I still own a IIXL+. I also have a III Mk2. But, the IIXL+ is a legacy product. It still sounds good, and enjoy it for what it is and you should too. Stop wishing for something that is not going to happen. Fractal cannot wave a magic wand and give you what you want.
You have it from the man himself, there won't be any more updates. What else do you need?
