Pro Tools 12 is fantastic. I am not so sure that your 002 still won't work even though it's not officially supported. I don't know if you realize this but if you buy or upgrade to PT 12 you actually get included licenses for PT 10, 11, 12 and "2016" (still not sure exactly what PT2016 is exactly) so you can still run 10.3 if you actually do run into compatibility problems with your interface and you want to back out while you upgrade. I think there is a good chance though that your 002 will work even if it's not officially supported anymore. A lot of times that just means they have stopped testing that hardware for newer versions of PT, not that it necessarily won't work.
