Bah!. Thx a lot.

Which one is dual boot CE/LE? 

Mecool KM3 / KM9 Pro.

Beware the 2GB KM9 Classic has rubbish WiFi.
Both have no Android TV Netflix App support.

Thank You very much.

And last question. According to my demands: HBO GO support and dual boot LE/CE. Which next generation upcoming Android TV box with these features is announced to be on market? 

Unlike Netflix, HBO GO does not have such restrictions on which device that it supports, at least it didn't use to.  I used to use it a couple of years ago on one of my Mecool boxes.  

I don't subscribe to HBO Go now, so can't fully  test, but it installs and shows thumbnails, but could not actually test it to see if it plays.  I tested on my Beelink GT1 mini 2 running an ATV mod from Minixfreak (it supports Goolge Widevine Level 1 with HDCP 2.2).  I also tested it on my Beelink GT King Pro running the ATV mod by Alvatech. 

To be noted, both of these Beelink boxes were provided to me free of charge from Beeliink.
