Well to be fair, Sony had awful marketing prior to the PS4 (well, for the last gen really). The PS3 had great games but were either marketed in a bad way (Resistance 3) or had no significant marketing at all (Sly TiT). I think that's a big reason some of these games underperformed. I still think third party games will on a whole sell better, but that's fine.
Plus, Sony's games are not necessarily drenched in the "shot gun" approach, with the exception of a few games. And they take chances with new IPs. Their games won't appeal to everyone. I honestly prefer this approach than relying on the same series over and over again.
Playstation = The Beast from the East

Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
