One of the things that made Starcraft so great was that Blizzard put early dev versions of the game before reviewers, who ripped it to shreds and wrote it off as just "Warcraft in space." It's funny how Blizzard made sure no one would say that about the final version...
Blizzard actually listened to a lot of input from the outside before the final release of the game. It's all on Wikipedia, along with some pics of the early builds. I know the video game market isn't what it was in 1998, but I can only imagine (hope?) there's still a lot to be gained by developers trying to get as much feedback on their product as possible before release.
Maybe they're not exactly popular, but I would hardly say they're dead. Just from casual observations, I've gotten the impression they have at least a small institutional presence.
Most recently, I visited a SUNY (State University of New York) and they had a whole fleet of Segways there. As you walked around the campus, you'd see the police scurrying around on them giving out parking tickets. I couldn't help but chuckle every time I saw it, but it seemed like a complete waste of resources to me considering the sorry state of the campus.
So, if at least for the lazy ticket givers of the world, Toyota isn't entering a market completely devoid of consumer demand.
Nothing motivates a man more than to see his boss put in an honest day's work.
