I've seen some Windows developers getting advice on the protocols used to talk to the watch on their Slack channels. I don't think you'll see Pebble implement a Windows host app, but they've not been too hostile to the idea. The watch-to-phone communications methods are the same with the Pebble Time Round. It looks like the differences are all in how the UI of the watch is rendered, and those are pretty major. However, outside of the screen, the hardware is very similar to the already-deployed Pebble Time.
