Like people already stated Gex, Sir Dan, Tomba, Croc are certainly characters that deserve to make a comeback.
But then again who owns the rights of these games? Who is going to develop them? Does this generation actually give a fuark about platformers or is it all about shooting? I would love to see classics like this make a comeback but I don't think it's possible.
Pit got a comeback because he was in Brawl. MediEvil and Ape Escape could make comebacks on PS Vita
