For that matter it´s unlikely anyone else in the dedicated videogame market will reach such heights either. DS and Wii individually have been more successful than something like PS4 in a similar timeframe. To do well you don´t exactly need to perform record sales. But I see no one make the silly claim that Sonys videogame business is performing badly despite generating far less profits in comparison.
As long as they deem the performance decently profitable enough, there´ll be continued support and new products in the same vein. If not you get news like today, with PStv getting killed off in Japan and PSV likely sharing the same fate in anot too distant future and the probability to be a dead end when it comes to future handhelds by them.
Basically the difference is future products vs the danger of no products.
