Perhaps, though, it might be best to wait and continue to enjoy your T2 until all the parts of the Audya that Ketron say are coming finally get here (editing tools would be primary, I would think) and the majority of the bugs squashed.

Let someone else be the beta tester for you, Jose! Don uses other arrangers as well (you gigging solely on the Audya yet, Don?), so those bugs may not be gig breakers for him. But if you sell your T2 to get the Audya, they may be more important than he makes out...
