Have you never seen or heard of the Wii virtual console or any of the Sega\Actvision\whoever classics collections? Just because they don't sell them right now or expect to make money on them in the next 20 mins doesn't mean there is no money expected from them in the future. With the current copyright law the future is for fucking ever, and who knows when the next round of nostalgic resurgence is?

Just like the Disney vault BS, absence makes the heart grow fonder.
