I doubt he will be the biggest hardest boss, just like with any game, story, show, anime and even life. There is always someone bigger and badder. They wouldn't release the most powerful boss this early in the game. It would just make the rest of the game boring. What's going to happen is they will create some shoddy loosely connected story and we will have new gear, a raised level cap, and super Sayan 3 in a way. If I was to put it in Dbz terms, it will be just like wow and every other mmo that has ran out of things to do. They will create some new distractions and give us a new lvl goal to grind too. All that stuff is fine, if they could at least put at least a tad bit effort into the story, and reading short little grimore cards doesn't satisfy me. It's hard to feel immersed in a game that only tells you shoot this shoot that. It's dark your light, so kill it. I feel like the story was written by a child with a crayon and some guy came by and was like hey I can sell that. $$$$$$$$$ just saying lol
