That is the dangers with emulators, if they work to well then no one will bother developing native software.
WineX isn't exactly an emulator, and let's face it, porting games to Linux has already been done without much success.
The way to combat this is to provide technology which is good enough to encourage people to develop for your platform and port it to the more profitable ones. Doing it the other way round just doesn't make financial sense.
The Amiga isn't even in the picture. There simply isn't enough of an Amiga market to support any sort of modern gaming industry, not even one based on ports.
