If you pre-ordered the Watch Dogs PlayStation 4 bundle from Amazon in the U.K. then don’t worry about not receiving the console at launch because Amazon has resolved this rather last-minute problem which was caused by the delay of the game.
If you go to this link, you should see the same page as when you selected your bundle choice the first time, though you will notice that there is no bundle two because that was formally the Watch Dogs pack. Copy and paste your PS4 order number from your open orders page or an email and select one of the bundles and you should be set for launch.
It’s good news that Amazon has been quick to resolve what could have been quite a big problem for PS4 early adopters.
