I've voted "other" for the following reasons:
1. there was never any AAA chipset produced, and it wasn't going to be backwards compatible with OCS/AGA so that would be pretty pointless.
2. I'd much prefer a wedge/keyboard case than a big box.
3. FPGA for the CPU and AGA chipset maybe, but then it would just be another Minimig so why bother.
So here's my "other" suggestion. Use FPGA for the graphics but make it reprogrammable from software. Initialise it with AGA core from ROM, but allow the user to change it.
Also add a standard PCIe graphics set from nVidia or some other vendor, so we can have the latest OpenGL graphics. Pipe the output of this through the FPGA graphics core so it can process the image including "GenLOCK" the AGA on top of it.
The CPU could be FPGA-based 68060-like (special Amiga friendly version!) or I suppose it could be an ARM or PowerPC chip with software emulation. But I like the idea of an FPGA at the moment because I'm thinking of making my own core.
I guess this is really a combination of 1 & 3.
