This is exciting because the current defacto standard for upgrading the graphics in a TI-99/4A is the F18A project, which is an FPGA based solution. It's really cool, but it's expensive and frequently unavailable.
I am interested to see if this project evolves in the direction of F18A compatibility. It will need to support 80 column mode at a minimum before I switch.
I'll certainly be looking to add some F18A compatibility in the near future. Like you, it seems the overwhelming majority are primarily interested in 80 column mode, so that will be first up.
