This is interesting, but I can't say I really understand a lot of it.
So the GC was in development as early as 1998? That's very interesting to know... That was only 2 years after the release of the N64. Did Nintendo see the N64 as a failure? Would that be why the GC was put into development so early?
It also makes you wonder what Nintendo has in the pirpeline right now, hardware wise. They typically don't announce new hardware until just a few months before release, so for all we know they could have a VR headset being prepared for the Wii... that would be interesting.
