Hrrm. I think there will continously be a small influx of new folks that never had an Amiga as a kid, drawn mostly to the games that came out on the Amiga, like me.
I never even knew the Amiga was meant to be a home-computer even, I just thought it was another console. Sort of. ( bit odd that a console had a keyboard...)
Basically, there are fans of 16-bit gaming, and sometimes they deplete games of interest on the Mame, Snes, and Genesis and then they sometimes find the Amiga, and then they've got a whole new platform to discover.
