To be fair, those old people didn't have much to go by. Gen 6 was not very representative to predict anything from it.
Then again Gen 7 will probably have nothing much in common with Gen 8. But since people already realize that Wii was a fad and recognize the strong brand of the Xbox the predictions for Gen 8 should have more perspective.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
