Its been to long now Crash Bandicoot is and has been for long time DEAD. Its not coming back and i really don't think naughty dog would make it even if they could which they can't because activision owns it meaning sony would need to buy the series and its probably not going to sell very well.
See you in Valhalla
I know this is an unsual concept for many in gamerdom, but what if Naughty Dog doesn't want to make another Crash game? All I keep seeing is "THEY HAVE TO MAKE ANOTHER CRASH GAME! THEY HAVE TO!!", well first off, Sony doesn't own the rights, those are still owned by Activision. Second, been there, done that. Creative people have the right to do whatever they want. I'm not a fan of Metalica, but if they wanted to make a calypso album, they have that right, and the "fans" don't have any business telling them not to. As a fan you have the right not to buy it, of course.
Creative people need to be free to create without intereference. Design by committee doesn't work.
