A funny thing, this thread asking of an E3 that happened nearly a generation ago. I was recently reading old EGM and Nintendo Power mags just for fun and stopped around 1995 the last time around. That E3 was... really something. Sometimes you meet curiously interesting insights, such as executives speculating on hardware much like the Switch and the Stadia back in 1989 or so.
Parts of the hypothetical future are bound to happen, I suppose, because we dream about things that our brain can actually perceive happening.
