Hello people! I reccomend (misspelled?) you go to my Kirby Wiki profile for information regarding me, because all I am going to say is about SSB4.
About me
I am a huge Kirby fan, so please keep that in mind when I mostly talk about his series.
Possibilities for SSB4
I don't know the: exact name, the release date, or ESRB rating. (Probably T)
Character possibilities
They will probably add a lot of Female characters, considering the fact that there was only 4.5 in Brawl. (Peach, Zelda, Samus, Nana, and Jigglypuff) Likely newcomers (Female) are Daisy35%, Dixie Kong45%, Mona55%, Kat & Ana75%, Brittany25%, Wii Fit Trainer100%, Krystal85%, Toggle-able Pokemon Trainer15%, Lyndis70%.
Likely newcomers (Male) are King K. Rule45%, Waluigi75%, Sylux50%, Bandana Waddle Dee75%, Magolor45%, Knuckle Joe40%, (Most of which are playable in games more recent than Brawl) Awakened Mewtwo95% or Zoroark95%, Victini20%, Genesect50%, Chrom75%, Pac - Man35%, Little Mac75%, Mega Man100%, Villager100%, Isaac45% Tails30%, Shadow70%, and/or Knuckles50% (assuming they keep Sonic which looks pretty evident right now).
Characters they may drop: Toon Link99%, Wolf85%, Lucario100%, Ike95%, Lucas75%, Sonic35%, and Snake85%.
Confirmed returning characters: Link, Zelda, Ganondorf, Mario, Luigi, Peach, Kirby, Pikachu, Bowser, Donkey Kong, Samus, Fox, Olimar, and Pit.
I REALLY hope they add any, just ANY new Kirby characters. Namely Bandana Waddle Dee. I love Bandana Waddle Dee. I think my percentages are pretty accurate. But a few of the assist trophies that don't come to my mind might make it in as well. Obviously this is a wishlist for the most part, but I REALLY don't like Tingle, nor is he likely to appear playable. Don't get mad at me for this, but I don't think they will add too many new (playable 3rd party) series' to SSB4.
Stage possibilities
Battlefield100%, Wrestling Ring thing100%, Cookie Country80%, Giant Chasm80%, Castle Dedede55%, Skyarrow Bridge30%, Bottle Ship30& (with Phantoon), Temple of Time45%, Skyloft100%, Animal Crossing Map100%, Other Animal Crossing City map100%, Mega Man Map100%, Some other Skyward Sword/Kid IcarusMap 99%, Gerudo Valley100%, Spirit Tracks Train100%, Sparkling Waters30%, Bowser's Castle75%, Factory (DKCR3D)20%, Some other Donkey Kong jungle map99%, Wii Fit Room100%, Yoshi's Island (4)99%, Cool city in X & Y45%, Some Pikmin 3 thing99%, Cool Fire Emblem map100%, Some Mother thing80%, Pac - Man65% (Game map with Ghost traps), Flat Zone 3 99%, Animal Crossing map45%, Mario Kart cows map10%, Super Mario Galaxy Starship99%, Nintendog map100%, and Some Sonic thingy55%. OK, people, this is obviously not completely legitimate. Percentages! OK, they're pretty accurate now.
Things I wish for (features in general)
I want to see a Mii character that's different depending on the user (IE, username "DEKU" could have Mii "Gavin" registered as the player's Mii).
A highly improved Stage Builder; you can use any snapshot taken in the game as the stage's background. I would also like to see Upside-down-able objects (like spikes), and maybe blocks of lava/fire, and/or maybe flamethrowers? Ooh, AUTO TURRETS! SUBSPACE EMISSARY RESPAWNING FOES/ENEMIES!
NO ADVENTURE MODE; it sucked and was a waste of memory. ... although I did like killing Tabuu... ...or they could make it better...
Things I wish for (characters)
Dixie Kong, Krystal, Toggle-able Pokemon Trainer, Blaze, King K. Rool, Sylux, Ridley, Bandana Waddle Dee, Magolor, Knuckle Joe, Genesect, Chrom, Lyndis (I'm hoping they replace Ike with Chrom and add Lyndis for three Fire Emblem representatives) Shadow, Eggman, and Tails.
