Magnum Mania!

Has anyone heard about this happening?

I am tempted to replace my early seasons double sided discs with the single sided ones, but if Blu-Ray is coming then I'll hold off.

I did a few quick searches but didn't turn anything up.

I wouldn't count on it anytime soon. There doesn't appear to be very many 30+ year-old TV shows that have a Blu Ray treatment. There are some, though. Maybe more in the future?
