Software has bugs. That's just how it is. There are millions of lines of code and in those lines of code there are mistakes, or there are hacks to meet deadlines, or there are misplaced strings, or there are memory leaks, etc. No matter how much QA goes on things will always get through because either they were missed completely or found but deemed of low enough priority that the release could go through, regardless. No matter which company is doing it this will ALWAYS HAPPEN.

As an example of this, Microsoft just released Windows 7 a few days ago. After paying around $200 for it, everyone in the world fully expects Microsoft to continue updating and fixing this software for the next decade, and that's without the consumers even spending another dime! Apparently what you would propose is that Microsoft should push back their release for 10 years so that they can get every bug 100% fixed. It simply does not work like that.

I expect the FE team to be working on bugs for months, even years, at which point there will still be some bugs, and I'm perfectly fine with that. It's just how software works.
