Got this email from them today XD
Hey Mr Bigpoppaad,
Thanks for your following order placed with Gamestation.
You'll never guess what!! The UK release date for Left 4 Dead 2 has changed to 20/11/2009 00:00:00. This happens quite often and we know it's frustrating. It's just one of those (infuriating) things which are unfortunately out of our control.
Don't worry though, your order hasn't gone anywhere and will be sent out just before its release date via the option you chose - just hang on in there a little longer!
