To answer the OP quickly and succinctly, there is no need for an FPGA-based VCS. We're covered by ebay, Flashbacks, and emulation.
Additionally I also feel that if new VCS hardware were to be made today in the form of a full console; there would have to be additional things included. Why? Because! And that's a problem, WHAT to put in, what sort of "add-on" features to incorporate?
Keatah, with all due respect, you have made it obvious in your rants that no console truly needs the FPGA option, because emulation is cheaper and more feature filled. However some gamers demand tighter control, which can only be had through the FPGA.
