After reading Doug's review of the new lighter, smaller and better McMurdo PLB it occurred to me that perhaps there might be a new edition of the SPOT on the horizon. Reason being, I do a lot of solo hiking and would love to be able to send my family the "I'm OK" or "OK but running late" messages, but the glaring deficiencies of today's SPOT have kept me from using it. The McMurdo PLB sounds like a fantastic tool but it's only for full-on emergencies.

Have you guys picked up on any planned improvements to the SPOT?
