I recently had a discussion with FLYGVA where we wondered if Superpoints expire? Does anybody know?

I have plenty of Superpoints, but as I also have plenty of M&M miles I was so far reluctant to transfer my Coop points, as this is a one-way street. Instead, I figured I'll just keep my options open by keeping my Coop points, which I can redeem for other stuff (namely: JU-52 flights) as well...
