No Jiggs? Are you insane?
Yes, yes I am. *Evil laughter*
Four Fire Emblem characters and all of them are sword-weilding lords? Why not Robin or Anna? For that matter, why Lucina over Chrom?
Lucina over Chrom? Because I have a huge bias against Chrom, I find her more unique than Chrom, and she's as important to the story as both Chrom and Robin. I also wouldn't mind Robin or Anna (heck, I had Robin on alot of my rosters before)
Snake's a bold choice. Especially after Sakurai mentioned how amazing it was to have Mario, Sonic, Mega Man, and Pac-Man together. I would like Snake to make it back, but I don't think it's happening at this point bar DLC.
I can imagine Snake being one of the last characters revealed, and I don't really find having Mario, Sonic, Megaman, and Pac-Man being found amazing hurting his chances, Snake still has almost no reason to leave.
Is there a reason you doubt the Sal leak?
I take all leaks with a grain of salt, and it's still possible for it to be fake, although it does look very likely at this point in time. That, and I just don't like rosters that have all of Sal's characters, as they seem to lake creativity to me.
EDIT: Also regarding Sal, his information (if true) is obviously outdated, so any character who he's says is playable could have been scrapped, or outright replaced.
I like the pick of Captain Toad, but I doubt he'll happen.
You can replace Toad with any other viable Mario character, as I know he's pretty unlikely.
