Finally I managed to saw one video review for new Keystone 3 hardware wallet, and btw what's up with manufacturers naming hardware wallets with number 3, first it was Keystone, than Trezor, who is next Bitbox or Passport 
Anyway, here is Keystone 3 video review made by Crypto Guide, I suggest everyone to watch it if you can, it's around 20 minutes long.
Important thing he notices about open source claims, Keystone said they will enable it later in November, that is next month so let's see what happens.
As of now Keystone 3 is still NOT open source device (yet).
