I don't think Roger will ever come back. The friction between him and Gilmour isn't whats stopping it, it's really between Roger and Rick. Roger basiclly told Rick that he had no talent and that he wasn't even worthy to play in the same band as him. That kind of thing takes a while to heal. If they ever did get back together though, it would be the greatest thing ever. I can see them releasing maybe one more album, but that album would sell in the tens of millions!!!
