For the most part, Megaman and Sonic would most likely be the only 3rd-party characters playable in SSB4. I have high doubts that Pac Man would be playable. I would actually expect him to be an Assist Trophy rather than playable. Though, there may be a chance that characters and stages that did not make the final cut (usually due to time constraints) may appear as DLC, though Sakurai has no plans about DLC until both versions of SSB4 release.
