I don't see it in the near future, at least from Nokia. Here's why:
1. Earlier this year Nokia attempted to partner with Sanyo. Would have been a FANTASTIC partnership, as Sanyo makes some of the best CDMA phones out there, but has a zero presence in GSM, and vice versa for Nokia. Things got rocky though when they started talking about what patents and stuff to share, so they broke up and Nokia announced that they were pulling out of the CDMA market entirely.
2. Qualcomm, Nokia's archrival in back-end cellphone technologies, holds the patents for just about every cell technology out there, specifically for CDMA. They have both sued each other repeatedly, and Nokia doesn't want to have to pay licensing fees to Qualcomm.
3. The two major CDMA players in the US are notorious for closed-systems, which Nokia's not a fan of. Specifically Verizon, S60 Nokias, with their full-open bluetooth, full web browser, heavy use of java, etc, are just not suited to Verizon's tastes. Sprint isn't near as bad, but they still have some differences.
Nokia just has never been big into the CDMA market and without it, still holds 34% of the WORLD cellphone market, with the next runner up, Motorola, being a mere 17%, half of Nokia. Thus, they don't care, and they don't need to care. Nokia launches roughly 40-50 models/year.
