This update seems to have made Snake even more awesome than he was when he was first revealed... I think it's down to the epic music update and seeing him stranglehold Ike that like. I can just imagine all the steamy fanfiction and fanart already!
I think it's good to see someone like Solid Snake in Smash, since he has appeared in more than enough Nintendo console games, fills up the "badass" quota, and opens up the doors to some more epic appearances from some mascots who generally wander around all of the consoles... I have no idea who is good enough to get in, but Sonic would be kinda nice I guess. Just so I can have endless fights with just him and Mario, just like what the child in me wants.
One thing I DO know however, is that this Naruto discussion that has somehow popped up here is UTTERLY POINTLESS, since Sakurai himself has said that he wasn't going to put in characters who originated from manga/anime, and that means poor old Naruto has no chance at all.
