Twitter poster @LeogringoD mentioned last week, with a photo of a Samsung sign boasting "QLED 8K Prepare to be amazed at IFA" and "See nothing else":

It's not news that Samsung's been working on an 8K set. The company first showed the Q9S at CES 2018 in January, and quietly announced in a presentation at the QLED and Advanced Display conference in June that it would be releasing several 8K models this year. But thus far, exact timing and price have remained a secret.
