Fwiw, I have four generations of Chromecast and they all still work. The only real difference between “Chromecast with Google TV” and the new “Streamer” is that it doesn’t have the attached HDMI cable, but has an Ethernet port on it, so I consider it a push. It’s about twice as big but still pretty small.
Yes and no, old model is obsolete, new model has a different name and is supported for now
