MM will go down, but who cares? I love my legacy MM. I would not pay $8000 for a reproduction but that is just me.
I also would not pay $8000 for AFM or CC even though they are nice games.
I also see a price semi crash for the new Sterns that people are already trying to unload such as Xmen, Avengers, and Transformers. Free up that money for MM and ST.
