Thank you! Yep I remember I saw some videos about it and noticed it was different, I'll give a try
MetaKraken, as Ace3000 said, Tigron is already included in any version of the game, while Van Uber is a digital exclusive ( maybe it's a digital exclusive pre-order though ). Btw I think that if someone misses it, they'll release it later as a mini DLC. There is a game I play called Dragonball Xenoverse 2 where happened the same thing. If you pre ordered it you could get a secret character, then some months ago they released it as a DLC for everyone that missed it, so probably the same thing will happen to Omega Collection
