It is just another pathetic, incremental update with faster processor. The $129 model is Wi-Fi only, no ethernet, and it is threadless. You have to buy the $149 model to get an ethernet port and thread capability for Homekit. I bet it still won't play Youtube HDR correctly. Plus tvOS 16 will cripple it. Meh...
I just ordered the Fire TV Cube 3rd gen 2022, and it is a decent upgrade to my older Cube. I'm getting really tired of the buggie, suckfest tvOS and Apple's smoke and mirrors updates.
