So I have a fan theory, and I want to see if anyone else thinks it's plausible.
So you know how Google released the ADT-1 at I/O this year? Well that was an ATV platform, but it surely looked like a Chromecast device, didn't it?
We also saw the Chromecast come back through the FCC with some boosted internals and the addition of Bluetooth. For a Bluetooth remote, maybe?
My theory: Oct 9th, Google will release a new Android TV with a Chromecast form factor with 4k in tow.
TL;DR: New Android TV dongle on Oct 9 with Pixel launch.
On one hand, I wish it were true. On the other, the ADT2 has the 905x chipset, and that chipset is so weak! Why oh why they keep pushing it!
