There was a thread about it on KLOV and JROK mentioned the price there and that betatesters now have their boards and if all goes well it will be ready for sale mid september:

If you'd read the site (which I would expect from a purist) you'd already know this but here's a paste and copy:
One of the design goals was to allow for the use of the SysFGPA as a straight replacement for an original boardset. To do this I've also built a couple of different JAMMA to Williams harness adapters specifically for the board. They plug into the original harness and seamlessly allow the use of the board in a dedicated cabinet. I've personally been testing in a dedicated Defender cabinet and, although I might be biased, I can't tell the difference.Basicaly, this board is simply the early Williams hardware on one single board. JROK has been developing and making replacements boards for the various parts of the Williams hardware, like the ROM board, the sound board. So, the next step was integrating it all into a single board (like he writes on the site).
It's running on the original processor, it's running the original game-code. The real hardware functions are put into that single FPGC chip and responds exactly like the real stuff. The only thing emulated is the sound, but even that is on a processor based emulation, so you shouldn't hear any difference. However, it's also possible to connect a real soud-board for the purists !
This is why I am so impressed with it: this will make the games run exactly like the original hardware. No emulation. You can either run it in a "general" cab, or put it in a Williams cab with the right adapter harness.
I bet they also make a nice match to the Multi-Williams CP's that are readily available...

If you'd prefer good joysticks and leaf buttons you can also get the panel and CPO separately...
