Did they officially say no to Ico?
Team Ico has given a statement (cant remember where sadly)
That having either of their characters [Ico or Wander] would be somewhat of a "disgrace to the character" due to the art difference between their games and All-Stars and would feel their character would not be properly represented.
Team Ico is very sensitive about their games and how their games/characters are viewed, so I doubt they will ever come to an agreement. So I think it's safe to assume its a for sure no.
I think that Abe is a very good guess. I don't want Joel though... I just don't think he'd be very interesting
Abe would be amazing & Joel I am ok with but I would prefer Ellie because the game needs more females plus from what I have gathered she is more important than Joel but in all fairness I would like to see a rep from The Last of us. We also need more Insomniac reps.
next dlc is kinda a wild card. i predicted kat, and wa lah. I Really Want raziel in this game, but see'ing as this isnt a wishlist, my realistic expectation, prolly dart, cloud, or abe.
Dart = very possible due demand (Would love him too)
Abe = very possible (Kinda would want him too)
Joel = I really dont want gun guy, i think he might have really strong character as in his own game, but wouldn't Fit this game
Spyro & crash = if activision stops being **bleep**
Ubisoft reps = Connor, Rayman (I think hes possible), Prince of persia and maybe someone from Beyond good and evil (jade)?
Square-Enix = Cloud (Sadly yes) Lightning/noctis (possible due being recent), Sora and guy from Rogue galaxy.
And finally Lara Croft.
These might be the ones with highest chances.
