I'm holding on for the FPGAArcade initially, although I might also get a Natami once that's completed. I think programmable logic is a great way to preserve old systems - especially when the same board can have multiple different systems running on it.
I used to have an A1200, and then around 2000 I had an A1200 tower with PowerPC board and graphics, but I sold that because I didn't have any time to use it, so hopefully it went to someone who made better use of it. Of course back then I was also hopeful of that first AmigaOne board coming out fairly quickly - which it didn't.
