According to the site 'Plus, it’s designed to last, even as the way we use Wi-Fi changes. It’s built to support a growing number of "smart devices" because it includes Bluetooth® Smart Ready, Weave, and Thread.'

It's difficult to find more info on that as a developer. Can you guys help me out?

Bluetooth Smart Ready is a stupid branding mistake. It means "This device can talk to normal Bluetooth devices and Bluetooth Low Energy devices." Bluetooth LE is apparently "Bluetooth Smart" now.

I don't think Weave and Thread are really in play yet (Nest might use Weave?). Weave looks like a protocol for phones talking to smart home devices, and thread is a network layer built on the same radios as ZigBee.
