It is a bit meh. You can see that for anyone on the fence they look at the 3 launch games, Knack, Drive Club and KZ, they could easily turn around and get NfS, AC and CoD/BF
The main problem is that all the big 3rd party titles are still on PS360, so those aren't going to really convince anyone
Sony hasn't really ever had an actual system sellers beyond Gran Turismo. Maybe Uncharted or God of War is getting there, but I am far from convinced. What got people buying PS3s was just the weight of the library.
The other thing to note is that you don't need system sellers to push your new console initially. The hardcore gamers will buy it for the first few months just because it is an exciting new console. Then when you get to March, that is when you want your system sellers, so there comes inFamous and Destiny.... with a little bit of extra content (together taking on Titanfall)
Personally, I will be getting Watch Dogs, Killzone, NfS Rivals (ahead of Drive Club) and maybe AC depending on the release date (if late November, I'll get it on PS3)
Sony better announce something at GamesCon, because looking a year past launch the Xbone has Halo and Titanfall, Sony has inFamous and some Destiny exclusive content, time for Naughty Dog to work their magic!
It is also important that 3rd parties move on from current gen to get people moving across, even if it does hurt them financially in the short term. Most important of all, release GTA V for next consoles R*!
