Their forced into a date from the publisher, and if you followed the blog, or really the blogs of most games you would realize EVERY release ships out the door with hundreds if not thousands of bugs. So sorry, thats how software works.
And it was slated for release today, Europe's a different matter.
I'm up to the mansion party chapter with the detective and I've not had a single issue. This is very weird, it's definitely not the game. One guy on my friend's list had a couple glitches and the other two playing say they haven't had any. Weird. Seems like this is a hardware or botched update download issue.
