The only limitations I see is the lack of imagination and economics. 

Doing another GIME chip or GIME like chip is just a matter of time and inspiration. 
Doing it in an FPGA vs an ASIC gives you flexability. Swap VDU cores and change 
register definitions and away you go. The Coco3 memory map still has enough 
room to add at least 32 more registers. So that partt is not tapped out. How much 
backward compatibility to the Coco 1/2 really becomes the stumbling block I see. 

The real limitations is the current Coco 3 motherboard. To many of the components 
used on it are obsolete. Not really expandable as it could be.
