Hey all! Thanks again for another round of good feedback.
With respect to NB-IoT, it's one of our favorite LPWAN technologies that we've researched, and would love to build an NB-IoT device as a successor to the current version of the Electron.
The long pole in the tent is not hardware availability (although the number of modules actually available today is extremely limited) but the global rollout plan for NB-IoT support on the carrier side. Most North American carriers are rolling out LTE CAT M1 well in advance of NB1 (NB-IoT), and most European and Asian carriers are leading with NB1 instead of CAT M1. The rollout is expected to happen throughout 2017, but it will likely be well into 2018 until we can talk about global coverage for either technology.
In other words, you shouldn't assume that an investment into an industrialized 3G Electron represents an active choice to not build on new LPWAN technology, just that they're being developed on alternate timelines. If you have more or new information that we don't have on LTE timelines, I'd be very interested in chatting!
