Bandai are probably doing this so we can gather medals to Dokkan Awaken to F2P one into An LR, the Zamasu event will probably be around too.

The celebration doesn't mention Vegito's event at all.

All we know is that he'll be on SSJ3 Gotenks' banner because he's Super PHY, and they also added SSJ4 Goku to make people happy.
