Yeah, this is exactly what I was thinking of. No one is going to pay near to the original price for what is just a simple reproduction of the original hardware for a classic system. If I really want an original SNES, I can buy a used one for $60 or less. And a lot of the original cartridges can be had for $15 or less. (depending on rarity) A simple reproduction just isn't going to cut it in terms of value. Not when it has an existing collectors market to compete against.
Now, if they released a new mini-SNES that took DS-style cartridges and had HDMI output, I would be willing consider a collectors edition like that. Another possibility would be to release a hardware configuration that never made it to the US. I would love to see a reproduction Famicom, with collectors editions of US-release games, but in the original Famicom cartridge form-factor. That would be a pretty sweet collectors edition.
