I sent an email to Marantz asking when the RC5000 would be out. Here is their reply: (See my questions below)

The RC-5000 will most likely now be shipping in February or March. Marantz decided to upgrade the software at the first of the year and release in the first quarter of '99.
Q's:
Does this mean that the programming software won't be out in early January?

Is there an actual software upgrade (OS) that is being done for the Pronto. If this is the case, how can I get it when it comes out, and what will it be fixing?
