Nintendo could only pass Toyota if they had a major decline over the next several years.
However, I think they'll catch Mitsubishi. Remember, Nintendo was only worth about 12-13 billion before they launched DS. They've grown about 6 times over already. And they're in the tech market where it will be easy to become overvalued, like Microsoft in the late 90s or Google today.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
Satoru Iwata, Nintendo President. Only slightly paraphrased.
