Well, since it is the final, final (hopefully) final fight with the main villain of the arc, any long-running shonen manga is bound to get a little DBZ syndrome... I was a bit worried about the series in the earlier chapters, when the author set up the final encounters with that roulette game, then just kind of ditched it after one battle.
I do have to agree, that whole "I'm only using half" rebuttal was pretty great. Hokey, sure. Cliched, sure. But still great.
So the real question is, will the series actually end after this?...
