Playstation brand is comparable to MTV it's fad hosting platform, they find their fad on MTV after few years the fad vanishes but the platform remain.
On the other hand the core is largely semi religious cult.
To prove my point, although PS3 greatly strengthened position recently every 1st party game released in last few years except Uncharted failed to catch sales, the last failure was God of War: Ascension beaten even by Luigi's Mansion on 3DS
