Think the leak is relatively accurate, but not 100% correct.
Would really like Snake back and right now he's at about 50/50.
There's no evidence for him but none against him either. This is true of others like Shulk, Chrom, The "other" earthbound rep, ROB, MetaKnight, Ganondorf, Falco, Wolf and so on.
Iceclimbers and Rhytm Heaven have smash run enemies.
Wario and Falcon have assist trophies linked.
Saturn and Badge are back which points to an Earthbound rep.
I would like if the DLC was in Packs for characters:
Melee Pack:
- Melee Retro Stages
- some New Stages to Rep the characters
- Dr. Mario
- Mewtwo
- Pichu
- Young Link (MM Moveset)
- Roy
Brawl Pack:
- More Brawl Retro Stages
- New ones
- Squirtle
- Ivysaur
- Others that are cut
WiiU/3DS
- Entirely New Characters and Stages
As you can probably tell, I am sour about cuts!
Could see them at the end just releasing another version later on with the DLC in it to try to double dip.
