So a MM remake was announced. That doesn't mean people are rushing to sell their CC. This game is likely not to be remade or if it is, it won't lower the value of the original for the following reasons:
1) CC doesn't have the appeal of MM. So it won't be as easy of a sell
2) Williams abhors software modifications such as CCC. Rick has stated that something like CCC cannot be allowed by Williams. So a remake won't ship with this.
3) CCC requires P-Roc. It seems unlikely the this will support the new chipset - ever. It sounds like the old style driver board and CPU board are going to be unified. A P-Roc would be impossible since it only supports the CPU board side. There are more differences that are problematic such as no lamp matrix so wiring on the CPU side will be drastically different. These changes further make a standard wpc95 driver board unlikely to work. Someone could replace all the boards with old style, but he would also need to get ahold of an old wiring harness. And then he would need to mount lamp sockets and wire them all. Then who knows if the input transformer even is set up correctly. I really think P-Roc is out here.
4) This makes CCC impossible. It's not a "they'll figure it out". It's a deal breaker. No CCC, the demand for a CC that can run CCC stays high.
Therefore, I think its likely a remake won't happen for CC. And if it does, its years away and it won't cause CC to be $5000.
Finally, the entire pinball market did not collapse due to one remake. MM will be out next year. If someone wants an AFM, there's no announced AFM and if one comes out (likely in my opinion) it'll probably be 2015. That's a hell of a long time to be waiting around. I don't see any of the remade games selling for under $7500, probably $8000 no matter the title. A fish tales cost as much as a MM to make.
I disagree that you represent the supply side of the CC market. I doubt anyone will sell you a $5k CC here. I'd take a $2500 BBB. That doesn't mean I represent the supply side.
Finally, if anyone has a beater CC, I'll pay $6k now and if the playfield is pristine, $8500. I doubt anyone will take me up on these offers but they're $1k more then you're offering which should definitely seal the deal.
