[Coco] Any news on the so called CoCo4 or Next CoCo project that Bjork was heading?

Personally, I see the FPGA solution the Gary Becker has created as the
best "CoCo 4" experience available.
It's hard to describe how amazing it is to use.  I am not one to buy
into the "user experience" hype normally, but using the CoCo3FPGA on
and Altera DE1 feels "real".  It feels like a real CoCo in a way that
no emulator ever has to me.
It turns on and offers the OK prompt instantly, just like a real CoCo.
 It resets instantly with the push of a button, just like a real CoCo.
 And.. there is more to it than just that... hard to put into words.
One example I can offer is that although I've had emulators running on
my PC for some years, I never bothered to mess around in BASIC like I
did as a kid.  The very first time (and several times since) I turned
on the CoCo3FPGA, I was just draw to it.. started writing little BASIC
programs and experimenting, remembering the stuff I'd done as a kid.


Why use a general purpose PC, with all the extra overhead and
configuration needed for even the simplest emulator only
configuration, when FPGA hardware can be put together more cheaply and
can provide a better CoCo experience.  I am not a hardware guy, but it
would seem creating adapters for connecting real coco peripherals to
an FPGA board would be simpler than some PCI or USB solution as well.
