I'm curious if this means Tiga will get a proper voice actor or Hiroshi Nagano will return. The former is the most likely though.

Oh, you can bet that 2021 Ultraman will have his name ends with "-a" to go along with Tiga, Dyna and Gaia. Ultraman Giga? Magna?

And it seems that Alpha Edge will be 'obsolete' and Z will be represented through his Original form like Nexus Junis and Orb Origin did.
