I think disconnect between the success of the PS4 and people's assumptions that it doesn't deserve its success because it has no games has to do with people on GAF (and in the gaming media) being obsessed with the notion that first-party titles/exclusives are the definitive system sellers.
Yearly franchise blockbusters are regularly disregarded on this forum as being "same old shit" but it is precisely those games that are selling the new generation systems. 10M people aren't buying the PS4 to play Infamous, Killzone, or whatever indie exclusives Sony can round up. They're buying it for Call of Duty, Assassin's Creed, Madden, FIFA, and soon Destiny.
I think people are just severely overestimating the power of an exclusive game, especially in relation to Playstation/Sony, which has had the weakest first-party (in terms of sales) for some time now. People wanted a next-gen system to play their favorite 3rd-party games with higher image fidelity and simply chose PS4 over XBO for any number of obvious reasons (price difference, dislike for Kinect, DRM fiasco, XBL/TV services being heavily catered to USA/UK, ect.)
