Yes, the release date got pushed back. They had originally planned to release it in the Spring. They have made poor/somewhat insulting excuses as to why it was delayed, but honestly I think the real reason was because they needed to. But you can't tell your shareholders that! lol
Hopefully, the delay will mean they will fill the game out more then it was originally intended to be and we will get a better game in the fall. :)
As for Sims 3, yeah it is full of bugs and glitches. I don't think it is exactly because the devs didn't care about quality, but between deadlines and a horrible game engine. Hopefully, the Sims 4 engine will be better and more adaptable.
