There are 122 games out right now for the PS4...
But I can only agree with you, the "free" PS+ titles we had so far are disapointing, most of them I barely played, nor was I interested, if I did not get the PS+ 1 year card recently I would not have renewed it... I figured that I would be better off spending that 50$ on games I actually wanted to play (I don't play online).
As for keeping the PS3, I sold mine a few months ago and there is no going back, the generational leap seemed too drastic for me to ever want to use it much again, and I am expecting Sony to re-release most of my favourite titles sooner, so I will get them back in better shape! (mind you, I also play on PC and the PS3 was only ever used for exclusives/indie titles and media streaming, it never impressed me).
Now the PS4, well, if you are not in a hurry, wait until the price drop or for a good deal, if the price is not cut before Black Friday it will be very early next year...
As for me, I really enjoy the games I got on it so far, even if many are "just" games available on older consoles that run better with more details and an an higher resolution.
