The problem that FPGAs have is that they are only good for low-volume solutions that require flexibility and have no power constraints.

That's a really narrow market. Telecom equipment and lab equipment, basically.

If I need volume, I need at least an ASIC. If I need to manage power, I need a full custom design.

MicroSemi (now part of Microchip) makes some low-power FPGAs. Xilinx has made the coolrunner CPLDs for years that are mighty low-power (they're not huge, but often are big enough for some needed extra logic.). (Another not care too much about power is Military.)
