I'm pretty sure that Etna won't be involved (nor would Sora; Square's NOTORIOUS for that) as they aren't as Playstation Exclusives as it seems. And both are popular in this department, but for a Smash Bros clone (ripoff is a loose term; code-for-code perfect match)
1. Disgaea DS (Nintendo Handheld). This and that cellphone game. The netherworld of Disgaea used to be playstation exclusive, but it's appearance on the DS practically lost it's right to be called PS Exclusive.
2. Kingdom Hearts is a crossover game. Fat Chance trying to get that license from both companies (disney and square, respectively).
3. It would practically be a battle of the unknowns at this point; Jak, Sly, Spyro, Ratchet & Clank, Crash are all PS1-era exclusives, now some are not, and these guys (and a few others) are practically the only ones I know about I could actually name on the top of my head when it comes to this. I don't even know if they are gonna add the Battlefeild soldier too, and half of these heroes don't really have names.
Most of the playstation experince I'm going through now is Disgaea 2, actually. Mega Man made up most of my PS1 experince (I was a Sega Kid, mostly, so I played those games more often on the dreamcast. I had a PS1, but not many games, and those games were mostly IPs I already knew about).
