I've been pretty much lurking during this whole leak (both here and Gamefaqs) and I haven't really discussed it with other Smash fans who aren't my close personal friends. Sorry if I go a bit off topic of whatever the current discussion is here, but I felt like putting my two cents in.
I was leaning towards real when the roster first came out. After the whole debacle with the Brawl roster and the multiple Pokemon leaks I've witnessed I have learned to keep an open mind about such things. That said, the videos obviously confirmed the whole thing and then the recent batch of pictures only cemented the truth.
The newly revealed characters are all pretty cool. I don't know much about Shulk, but he seems fun (I didn't even know he was british lol). Bowser Jr. I have wanted in the past, but I didn't expect him to be done like this. The Clown Copter is a brilliant way to implement him. He looks really fun to play. Dark Pit seems a bit like a waste of a spot to me. I'd need to see gameplay of him, but I'm sure he'll be interesting enough at least. Duck Hunt/Duck Hunt Dog is a really cool idea. I am looking forward to more info on him, especially how he plays. Bringing Dr. Mario back seems odd to me. I guess it gives me hope for Mewtwo, since it shows Melee vets CAN return. But he is also going to annoy me if Mewtwo doesn't come back after all. ROB actually surprised me in coming back as I was sure he'd be cut. Losing Wolf, Ice Climbers, and Lucas kind of sucks (especially Ice Climbers, though I won't miss the infinite). Hopefully they return as DLC. I kinda figured Snake, Squirtle and Ivysaur wouldn't come back. Ganondorf being a clone makes sense to me. His "Falcondorf" moveset is iconic now. I mean doesn't Sakurai main him? Plus he'll have new specials in customization I'm sure.
I'm still holding out hope for Mewtwo and Ridley. There seems to be space in the leaked roster shot for a few more characters. I know the whole Mewtwo, Ridley, and Dixie (sometimes Impa and Chorus Men too) rumor has yet to be proven real and is likely not so, but I am still hopeful. Mewtwo is heavily requested, which does not guarantee anything but it should at least put him on Sakurai's radar. Same goes for Ridley. Mewtwo is also a Melee vet, and if Dr. Mario can come back from that, then why not Mewtwo? Dr.Mario is a clone and thus easier to include than a new/unique moveset character sure, but I still wouldn't rule out Mewtwo. An updated version of his Melee moveset along with Lucario's Final smash from Brawl or Mega Mewtwo Y shouldn't be that big of a task to include. Then again I never made a game. Ridley is a slightly different case as he'd be a brand new character pretty much. Though based on size projections from the April Direct, he seems to be scaled down quite a bit from his brawl boss model. That leads me to lean towards playable. Though I won't be too torn up if he doesn't make it in. Dixie and Impa would also be great additions. Impa in particular I really wanted in, but kinda lost hope for once Sheik was confirmed. Chorus Kids I don't know enough about to really want them or not.
I definitely do think there are a few more characters left to be seen. There is the space for them. Plus apparently All Star mode isn't unlocked. Sure Nintendo could just unlock all the characters and bypass unlocking All Star mode, but that doesn't seem as likely to me. I mean why not show off all the modes to the ESRB? I have a friend who plays a ROM of Brawl online. He has to use cheats to unlock the roster since the ROM doesn't save or something. He tells me everytime he does the cheat All Star mode gets unlocked too. Sure this is a farfetched example that doesn't directly confirm anything with a brand new game, but it still leads me to believe that All star mode is only unlocked when the roster is complete and will do so no matter how the roster is completed. So unless All Star mode isn't unlocked until you have DLC characters or something like that, I still believe we have a few more unknown characters. I am hopeful one of those is Mewtwo, as he would make the roster perfect for me.
All that being said it is also possible the video shown to the ESRB is taken over the course of a playthrough of the game. And the All Star mode pic was taken during the beginning of the playthrough, while the Roster pic was taken near the end. This is an entirely logical possibility. It wouldn't surprise me in the least if the roster we have now is the final one. I was hopeful the Brawl roster had more to it and it never did. "We don't get fooled again." I am hopeful for a few more characters that I was hoping for, but I am prepared to be disappointed and settle on this roster. Overall it is pretty good. Despite no new reps for DK, Metroid and Zelda, it has some pretty amazing newcomers and vets. Plus I'm excited to play as buffed Charizard and Lucario. Just fingers crossed we still get Mewtwo, Ridley, Dixie, and Impa.
