i really doubt the company would offer a trade in...it's not like they need to do a recall because the original was faulty...it just didn't have all the features that we as tapers (a pretty small demographic really) wanted. it would be a nice gesture, but think about it, what would m-audio do with all the 1st gen microtracks? what use would they be to them? they're still a pretty decent recording device for amateurs, even some pros who don't need 24-bit seamless recording. i would still use it at 16-bit anytime, especially in a stealth situation (if i ever stealthed, which i only have once, and used the MT and it was great).
i'm excited to see what they come out with next, but remember, don't expect them to bend over backwards for us tapers. they've done a really good job being receptive to our needs and making some changes in the firmware, and have probably even taken our advice for this next version, but we aren't their only market.
