I can't believe noone is asking about voice recognition! I don't care about anything else (altho more ram would be sweet), voice recognition will dramatically change the whole unit. No matter how good you make the current interface, it's still going to be a pain to access thousands of tracks with a few buttons. To be able to say what you want, and get it.. I don't care about the radio, I don't care about any twirly knobs on the front. I want to talk to my empeg :)

Will the current units be able to use voice recognition?

Kind of a moot point for me anyway, there's no way I'm going to be able to resist a new model with a discounted price :)
