Well, maybe because you intimidate most posters? Well, the newer ones.
[COLLAPSE="Context, man"]Mewtwo? = Future Pokemon?
Roy? = Future FE Lord?
I'm gonna be honest, I can't make any conclusion here. There's a LOT to consider for these two series. Does Sakurai intend to cycle in and out the latest characters? Does he care about the ones he got rid of? What about the fans? What about Ike and Lucario?
There's a lot of ways to interpret what'll happen, but the only thing I'm confident about is that we won't see any other currently existing characters from these two series. No Deoxys, no Sigurd, no Darkrai, no Micaiah. Their chance came and went.
I personally think he'll just bring back Mewtwo and Roy and consider adding a new character to each series. It seems like he just wants to add a new character from each series on top of all the previous ones. I figure that since Jigglypuff is still around long after her moment of glory, Ness is still around despite Lucas being planned to replace him, and both were intended to be in Brawl. Plus, you know, Mewtwo was supposed to be in 64 so Sakurai clearly has a thing for him, and the localization team almost took Roy without Marth in Melee (then decided to bring Marth since it didn't make sense to have one and not the other). They're also both really popular.
Anyway, these two are still up in the air for now.[/COLLAPSE]
Love that phrase.
