I think characters for the playstation future that arent established yet will deserve to be in. While this game is a foundation stone with all the major characters, the sequel will be for the playstation stars of the future, such as...
Kat (possibly in more games by then)
Jodie Holmes (Beyond:Two Souls)
Joel (The Last of Us)
Protagonist of The Last Guardian (If it ever comes out)
Possibly someone from Rain or the Unfinished Swan(unlikely)
As well as, in addition, some characters out already being more established in playstation history than they are now. Characters who dont quite deserve to be in this game but might in the sequel, aka Emmett Graves if he's given a bit more love.

Woah, okay SLOW DOWN a minute. The first game isn't even out yet and you're already talking about a SEQUEL? How about we play this game first and enjoy it for a while before we even think of another game? Besides, if this game doesn't sell well or is poorly received, a sequel will likely NEVER happen. Even if the game is a commercial success, the sequel wouldn't be announced for several years at best. It's not healthy to be rushing off to something new without enjoying what we're given first. It's especially not healthy to want a sequel JUST for more characters. Smash Bros didn't get Melee just to have more characters, did it? One more thing, didn't they say we'd be getting DLC? If so, who needs a sequel so soon as long as the DLC characters are cheap.
These are just the characters I think won't make it this time
Captain Blasto (Blasto
Jersey Devil (Jersey Devil)
Ethan Mars (Heavy rain)
Jennifer Tate (Primal)
Nathan Hale (Resistance)
Wander (Shadow of Collossus)
Toan (Dark Cloud)
Dart (Legend of Dragoon)
Carmelita Fox (Sly Cooper) [I want to see her playable]
Arc (Arc the Lad)
Toby (Kung Fu Rider)
Emmet Graves (Starhawk)
Robbit (Jumping Flash)
Jeane D'arc (Jeane d'arc)
Xia Covault (Kinetica)
Leonard (White Knight Chronicles)
Robed figure (Journey)
Tiger Shark (Invizimals)
Rau (Rise of Kasai)
Kutaro (Puppeteer) [I'm excited for this game]
Lara Croft (Tomb Raider)
Raziel or Kain (Legacy of Kain)
Big Boss (Metal Gear)
T'ai Fu (T'ai Fu Wrath of the Tiger)
Sony Imagesoft Characters
Humphrey (Altered Space)
Jerry (Smart Ball)
Realistically though none of these will make it.
