Based on the information you (Surety) insiders hopefully have, is 2Gig doing ok? I am concerned about the lack of a secondary panel for the GC3 and Internet based alerting. According to the article on CEPro, the GC3 panel was unveiled 4/2014. We are quickly approaching 2 years later and still missing a couple of what I consider to be pretty basic features.
I hope my worry is all for not, however, if the GC3 is a dead platform better to get out in front of it now.
Thanks.
The GC3, like the Go!Control, and like other manufacturer panels, follows a development schedule.
For reference, the 2GIG Go!Control Panel and the TS1 had around a 2-year release gap. (When 2GIG only had the one panel to focus on)
The GC3 is, as of the time of this writing, right around 1 year after release. And keep in mind the GC3 is not a replacement panel. The Go!Control (GC2) still has active development.
Development of peripherals like the secondary keypad naturally require insight into the market penetration of the primary panel. While I agree and was hoping for an early release of one, doing so at the same time as the primary would only divert resources and result in reduced support for both.
I understand the desire for the features mentioned. We are excited for their release soon, and I am personally a bit impatient for the Wifi support. I’m looking forward to the reduced latency for commands. However, the sky is not falling. 
We’ve been hearing rumors that the secondary should be ready soon. However I wouldn’t hazard an ETA.
