Agreed, they wanted to beat Xbox by launching before them, they have basically learnt from past mistakes that launching a year later is a bad idea. But you are right, Xbox has the more interesting line up at launch.
But as we saw last gen, the launch titles are not particularly important, it's the first party devs and exclusives that count later on in the consoles life, variety in games and the hardware's capability to last 5+ years, The PS4 has the upper hand here, although the Xbox has more interesting games at launch, that's precisely it, they are "interesting" not great, the PS4 just has less Interesting games so far, I'm happy to bet though overall in this race, Sony's console will have the better library of games, They are clearly making a huge effort with the PS4 and Sony have been the leader with the PS1 and PS2, they have the know how, they just need to apply themselves, the way I see it, I would rather wait for an amazing game (example: The Last of Us (PS3)) than buy a console based on a launch game (Example: Perfect Dark Zero (Xbox360).
Launch titles to me are important to get the console going and on the shelves for people to want the console. Though the PS4 moved a lot of units, I just personally wish I had a better selection of games while browsing the isle of games for the console.
If we look at the past, there has been many mistakes in console launches that jeopardized the console from being a great system regardless of whether it was good or not. Best example I can think of is the Sega Saturn which was a revolutionary system and honestly significantly better all around than that of the competing Playstation. It failed (well not completely, but it wasn't successful) mostly due to a horrid day one launch selection and general game selection for the first months of the console among other things. The console launch was not the only reason for that consoles failure mind you, but it was the start of a bad hand that kept them from doing well.
Honestly, I have been more of a fan of Xbox in the past and right now I still am because most of the announced games on this system are sounding better to me, but ive bought both consoles so the argument for me at least is going to come down to which console will I buy the multi-platform games for, which I have no idea at the moment. Right now the PS4 has one major game I want and have been dying to play for years Final Finatasy 15 (IE Final Fantasy Versus 13 renamed to 15) which is system exclusive. But looking at the system exclusives, neither has the upper hand because they both have a robust library of games that are exclusive.
Who knows, only time will tell, all I was saying was this is not a good way to start a launch of a console without some more games. I think the best part of the PS4 for me is the controller actually feels comfortable this go round which is a huge improvement over that PS3 controller which I always felt was awkward.
