You know, if you're considering going that far with graphic capabilities, then perhaps you should consider the possibility of creating a new console that's not really a ColecoVision. It could be backward compatible with all CV carts, and CV fans could buy it for that purpose, but it wouldn't carry the name "ColecoVision" at all. Then you'd be free to include any special feature you want in the hardware, and if anyone says "This isn't a ColecoVision", you could simply respond "Nope, but you can still play all your CV carts on it." From that point on, you can have more modern controllers that use connectors other than DB9 (USB perhaps?), have separate connectors for external keypads (this would be transparent to all legacy CV games) and if anyone wants to develop software that pushes this new hardware to its limits, they'll be free to try.
I kind of agree with Pixelboy.
Just thinking out loud here but, why not make a MSX2 video game machine that can play CV games. You could call it the Super ColecoVision. Have the port compatible with CV carts and sell and adaptor to use MSX carts. Or how about a computer add-on that turns it into a full MSX2 computer and call it the Super ADAM. I'm just saying. If you are going big, go BIG!
