This gen is one of the least surprising.
On the day Sony announced the PS3, everyone was horrified by the price and the launch lineup, and it sold poorly due to the price and launch lineup
On the day Sony announced the PSP, everyone thought it would sell very well, for a non Nintendo handheld, and it sold incredibly for a non Nintendo handheld
The DS was expected to win by a large margin, and it did. Sure, it sold slightly above most people's predictions, and the software is WELL above.
360 did exactly what is was expected to.
Nintendo's console was predicted to flop, then details got announced and the world was split into those who saw that it would do well, and those who didn't. Those who didn't are blind and most of them had to include negative sales in order to justify their wild claims. No-one took these people seriously at the time.
