Which one will fail?
PS2? Gamecube? XBox?
History shows that the market can only bear two competing console systems at a time. Any other systems fail commercially.
SNES vs. Genesis led to the failure of the TurboGrafx 16 aka the PC Engine, and the SNK Neo Geo.
PSX vs. N64 led to the failure of Sega Saturn, the Amiga CD32, the 3DO, and the Atari Jaguar.
