Two of the most requested 1st party characters within reason. Syphon Filter has been on PS1, PS2 and PSP and Bend are often rumoured to be working on a Vita installment. Legend of Dragoon nails an RPG rep which will shut a lot of people up.
wander and ico are way more requested then gabe logan.
Maybe you missed "within reason". We know Team Ico don't want their "art" sullied.
they never ever said they didn't want them in psabr.
I doubt there will be third party DLC unless it's from a company they're already working with. For example, since Namco lent them a Tekken character, Namco might also lend them a Soul Calibur character (especially since Kratos has already been in a Soul Calibur game). Capcom might lend someone else, but they'd probably want a lot for them.
As far as first parties, I'd expect a PS1 character or two (ones whose fanbases may have surprised Superbot, like Tomba or Gex) or more modern ones from games they want to be more popular.
I hope that they release "system packs" of dlc as themes in the future to keep reps over each system somewhat equal. I know theres only a slim chance of that happening but since thats what I hope for then Ill pick what I consider to be the most likely characters from each console.
PS1: Abe-he's not first party but I feel there is a string chance for him to make an appearance AND they could have a lot of fun with his move set. Dart-Everyone seems to want an RPG rep and he has the highest chance imo Blasto-I'm pretty sure that the game sold well and it would be an awesome nod to an old nearly forgotton franchise
PS2 Ico/Wander-Seems like the greatest missing franchise from PSASBR, I feel one of them will be in one day Dark Cloud rep-another possible RPG rep SOCOM rep-One of the most popular ps2 franchises certainly deserves to be represented.
PSP: Loco Roco-Would be an interesting character to play as Patapon-you cpuld have a single patapon or even a group act as one character Jeane D'Arc-A semi popular RPG published by sony, her lvl. 3 super could be her transformation.
PS3: Nathan Hale/Chimera-With how much representation Resistance already has it only makes sense to include a rep. Modnation Racer-As someone mentioned earlier have him fight from his car or heck, make that a super Lair:Seems as though that would be easy to aquire as they never made much money from that game in the first place
Vita: Escape plan-Either character would work well New Media Molecule game-I forget the name of it but that characters inclusion could be a smart business move to raise awareness for his game
As for 3rd Parties: Rayman Assassins Creed rep Ff rep Lara croft
PSP: Loco Roco-Would be an interesting character to play as Patapon-you cpuld have a single patapon or even a group act as one character Jeane D'Arc-A semi popular RPG published by sony, her lvl. 3 super could be her transformation. croft
