Okay, been seeing all the leaks, and decided to finally make a profile and confirm or deconfirm them. My long-time friend from college has some information he leaked me, and his source has asked to remain hidden, as he doesn't want any problems with the law.
-Palutena leak:
IS true 100%
-Demo leak:
Somewhat true, excluding palutena being an AT.
-E3:
Hard to say, lucky guess or not, but either way, all 6 are in!
New information:
Characters:
I know little about the roster except:
-All Brawl vets return, exclude Snake
-Chrom is indeed an AT, as a generic Avatar is a newcomer for fire emblem.
-Diddy and Dixie are a Tag-Team.
-Pacman is a newcomer, based on his looks from Pacman World 2, for example.
-Mii is in, with a moveset that is not customizable, but his FS goes with his color shirt.
Items:
New items I know of include:
-Burritos
-Zero-Gravity Boots
-Magnus is an AT
-Hawlucha is a new Pokemon, along with Gen VI starters and Xerneas, Zygarde, and Yvetal
Stages:
New Stages:
I only have one, based on the final battle of Kid Icarus.... and it is for Wii U AND 3DS.
Modes:
-Stage Builder is upgraded with plenty more backgrounds, lighting, and objects.
-Online is much better with host options, and private matches, along with custom matches.
-Break the Targets is back. As is Adventure, Classic, and Land the Platforms
Thank you, and goodbye! Feel free to ask questions.
