An announcement by Hasbro that an upcoming licensing fair in October for Europe will be digital/virtual/online... and it notes that 2021 will be the 35th Anniversary of Transformers, which I'm sure was meant to refer to the 1986 Movie anniversary.
With Unicron coming out next year and a number of 1986 characters rumoured to be released in the Studio Series line, this isn't much of a surprise... but a useful confirmation.
