Catching up:
I think there is no Mii Maga archetype, because there is no real mage user in Smash. Zelda would be the closest fit, but she isn't really a mage. There is no character who is a straight magic user who cast spells from a distance, hit hard, and dies if they're smack.
Personally, I want a character like that in the next Smash.
This is probably the biggest reason why I hate that Robin had to get saddled with a sword/blades. (S)He could definitely have brought something really cool just off of tomes and spells alone as much as I love the FE item triangle gimmick for silly reasons.
Don't remember where or when, but I believe Sakurai said something along the lines of "despite initially cutting up transformation characters because of 3DS limitations, I think it was for the better."
So I wouldn't expect to see Pokemon Trainer ever return. Ice Climbers are pretty much Sakurai's character so if he returns and the NX handheld isn't weaker than a gamecube then I'm sure they'll be back. If Smash sees a new director their chances may be up in the air though.
Yeah I remember this bit of info as well but couldn't tell you what interview it came from off the top of my head.
On other topics: Wolf and Ice Climbers (probably ICs more) will be back. Pichu & Young Link are the hardest sells but they have their fans. I could see Squirtle and Ivysaur's move sets coming back with some modifications as Blastoise and Venusaur just to make it easier for the team to do final smashes and for parity with Charizard. Snake... Snake has had a hard life. ;________;
On Ganondorf: You know, Project M tried their best to change Ganondorf into something crazier and I thought the sentiment was good but I actually wound up missing Warlock Punch when they gave him the float and made his forward smash a faster Warlock Punch. I feel like at this point, Ganondorf SHOULD be the brutish warlock, a dude that just disrespects with raw strength, but he should also finally have unique animations and even some twists on how things are done:
Neutral Special: Warlock Punch + Dead Man's Hand hybrid: He stands in place and collects energy into a large orb in his palm, when fully charged he leaves it hanging in the air in front of him then Warlock Punches it making it explode into a volley of X number shots depending on how long you held it. Getting hit where the orb explodes has power comparable to the current warlock punch.
Up Special: Twilight Warp: Flicks a Twili realm portal over the area specified by the player and gets destablilized and dragged into it before launching out of the portal in a lunge similar to the current uppercut he does if his current up B misses.
Down Special: Wizard Stomp: On the ground it's a single hit shockwave about himself similar to Donkey Kong's Hand Slap but with more launch force and cooldown/no rapid fire. In the air, it's the current Wizard Foot.
His current move set is equal parts too fun to part with and craving one or two little flairs to make it his more so than
vaguely his. I'm sure that everyone feels that Flame Choke (Side Special), dair (what I call "Thunderstomp"), ftilt (Sparta Kick), his jab (please make it more like Melee's though), and his up smash all feel fitting for the brutishness he embodies.The rest of his kit just needs to feel the same way instead of inspiring thoughts of "Captain Falcondorf".
Edit: Yea, I kinda don't want Ganondorf to become a sword character because I feel like a brutish warlock fits better and would be interesting versus other characters in the roster already.
