I thoroughly enjoyed my time with Google Glass, but then they stopped working (the screen is faulty) and I'm too lazy to send them in to get replaced. But rumor has it, Google is working on not one, but three new Glass headsets.
According to sources of The Information, Google is working on three next-gen Glass headsets, where one of them doesn't even include a screen. The audio-focused model is meant for the "sport crowd", making it a Bluetooth headset on steroids, in a way. Google is still reportedly working on an enterprise-focused model with a display, where I'm sure it'll be much higher resolution and quality than the Explorer Edition.
We should expect Google to unveil the new Glass headsets next year.
