A new Gran Turismo trademark has been discovered recently, and the filing's date seems to suggest that the trademark is related to the series' debut on PlayStation 5.

As spotted on ResetERA, the new trademark has been filed in Argentina on June 4th. The trademark filing includes the Gran Turismo title, its logo, and that of Polyphony Digital. As everything has been filed on June 4th, the original date for the PlayStation 5 digital showcase event, there's a good chance we will see Gran Turismo at the event in some capacity.
