TeamDokkaner has always been 100% correct in the past, but he also didn't mention SS4 Goku, so it's also possible that they'll do something similar to the Tanabata celebration, but with Future Gohan instead.

And we already know that the celebration won't be called Tanabata, since that festival is strictly Japanese and ended months ago, so we can't expect the exact same things that JP got.
