Simple, Sony will never be able to recapture their glory days on the PS1 and 2.
Even if Nintendo wasn't disrupting the industry, the company has focused too much on the core. They are not at a point where they can abandon it. Also, Sony is too late in the game in terms of software. Nintendo could survive because they had franchises people wanted. Sony does not. Most of the big games people anticipated were by 3rd parties.
