Gonna make a early guess and assume that the theme for the 10th Anniversary is "Kamehameha" based on the login unit we're getting, which is this Goku doing the move.
-Kamehameha is a 10 letter word and guess what anniversary we're celebrating in a few weeks? The 10th one.
-The F2P login unit we get for each anniversary hints the theme for it. The base Goku we got for 8th anni does a Spirit Bomb which was the theme. This Goku is doing a Kamehameha which could be the theme.
-Kamehameha is hands down the most iconic attack in all of Dragon Ball so having most known attack in the series to be the theme for the game's decade anniversary wouldn't be that bad of an idea.
For the headliners, Frieza and Super Gogeta can't be a part of it since they never did the move (unless Gogeta gets added if they make him do the move as a what-if unit), so they could do something like Super Vegito + SSJ4 Gogeta for part 1 and then part 2 is SSJ2 Gohan + Perfect Cell.
