Looks like InDesign 2.0 will follow in late February. Isn't Seybold in February? If so, a likely place for a formal announcement. The following is from one of their sales documents found in the same directory:
If you purchased an earlier version of InDesign between September 24, 2001, and February 21, 2002, you're eligible for an InDesign 2.0 upgrade for the price of shipping only. The upgrade must be for the same platform as your earlier version. This offer is available only through Adobe and applies to purchases made from Adobe or Adobe Authorized Resellers. You must provide a dated proof of purchase and your serial number when you place your order. Free upgrades must be claimed prior to March 21, 2002"
