Upgrading the McCormack UDP-1? Steve?

I recently talked with a McCormack dealer, who told me that because of lack of manpower at McCormack along with backlogs for the new UDP-1 Deluxe version, the upgrades won't be available until April; cost to upgrade shipping directly to factory being $850.00 plus shipping. At this time, I still don't know what the upgrade consists of. I e-mailed Steve a few weeks ago requesting information and received no reply, so I would imagine that he is bogged down with work. I have a UDP-1 that is about 2 years old and the dealer offered to take mine in trade for the new deluxe. The offer was probably a good deal, however, I asked him to give me more details on what the upgrades consist of before I make a firm commitment.
