ADOOM on A600 running 22-35 FPS

Since the future upgrades will be using an off the shelf development board with 128MB on it, that's the only realistic option for this generation of devices. The limited IO of the development board is almost certainly all being used to interface with the rest of the Amiga system and the peripherals on the daughterboard so adding more (really) fast RAM is a non-starter. If you were designing it from scratch you'd probably have at least 512MB but designing and building a board like that needs expertise, time and money. 128MB should be plenty for most tasks. How many people have more than that now on their classic Amiga? Has any 68k accelerator ever had more than 128MB as standard? It's twice as much as the Vampire 600.

Looking at the prices for second hand Amigas there must be a market for new machines at $200-300. You are never going to compete with the raspberry pi or the dozens of other arm single board computers on cost. What you could do is try and cut a deal to licence the Amiga name. A small desktop system baring the official Amiga brand with a real amiga 68K operating system and chipset but much more powerful than any previous 68k Amiga would be a winning combination in my opinion.

Also I read on EAB about Vampire600 V2, which is much much tinier, yet with bigger FPGA.

The FPGA is bigger on the inside but smaller on the outside, it has more logic elements but is in a BGA package, the first version used a PQFP chip. Other than being a smaller board (about half the height) and a little more headroom in the FPGA it should be very similar to version 1, maybe with fewer headers.
