Tomb Raider - Pre-order?

Tomb Raider already available for pre-order? But why?

Yesterday, as I was checking my e-mail, I noticed one e-mail from Amazon UK letting me know that Tomb Raider is now available for pre-order. How is this possible though? If you're interested in the game, as I am, you'd have read in a lot of places that the game isn't being released until the third quarter of 2012. However, since it's available for pre-order on Amazon UK now, does this mean that the game is being released soon? If not, this has to be the first time I've ever seen a game available for pre-order almost a full year before the game is due to be released.

Sadly, there isn't a release date listed on Amazon UK, so it's not possible at this moment to tell if the game is still being released in the third quarter of 2012, or is being released soon. I would really love to know though.

Does anyone know of the exact release date for the game? Has a release date even been announced at all yet? All I've heard so far is third quarter 2012. That would suggest it'll be available for purchase sometime between the 1st July - 30th September 2012. I've not heard of a more narrowed down release date so far. Hopefully, someone has heard of an exact release date, or a much more narrowed down release date.
