This is what has been posted on the DUC announcements forum…
Hello, all,Last month, I posted a note on this page stating our intention to revisit our decision to remove support for Mix-era peripherals in our next Pro Tools release. After reviewing the technical challenges and, in no small part, considering the needs of our customers, we have listened to your feedback and decided to retain support for Mix peripherals beyond the current 8.0.1 release. While I hope that this is good news for most of you, please understand that there are no guarantees as to how long we will be able to maintain support for these and other legacy hardware products. We will continue to evaluate compatibility issues like this and our commitment to you is to do our best to provide you with as much advance notice as possible when similar changes are required. Thanks again for your feedback, understanding and your continued support of the Pro Tools platform.

So it looks as though, at least for now, those using a Mix interface like an 888-24 on the legacy port of an HD interface like the 192 I/O will be able to for some time longer but it would still probably be worth looking at saving up for an alternative solution if you need that extra I/O regularly because I can’t see the reprieve lasting for ever.
