I reckon the CPS1 and roleplaying engine will have been out ages by then, and we will start seeing home grown RPG's. Loads more SDL ports too. Snes will probably be a lot faster, and PCE will have saves. I reckon quake will be available by then as well. Probably a couple of megadrive emus will be doing the rounds.Someone will probably attempt to tackle some of MAME, and maybe a slowish Amiga EMU will be in development. If the machine gets a Euro launch we will probably see some commercial games in English and other European languages. If it stays underground, probably no more games than the Koreans are releasing, and maybe some GBA ports as well. It would be nice if some native 3D games turned up as well.
If the Euro release goes well, we might see some peripherals as well, user installed FLU, TV out, mini keyboard, extra self powered storage etc, USB dongle to allow PC's to use GP RF frequencies. Maybe even a mini web browser/flash player. And perhaps even a 256MB SMC. But I guess it would have to go very well for peripheral manufactures to start making these items, they would all be relatively easy though.
And have a great holiday Dozer! I took my GP to greece earlier on in the year, and it came in really handy. Watched LOTR on the flight, listened to MP3's in the apartment before going out, and playing games on the beach, brilliant!
