Amazon have just announced that they're again taking pre-orders for PS4 consoles/bundles, including the "Gamer" pack with an extra controller, camera and Killzone: Shadow Fall, for £429.99. These aren't for release day delivery, but should be delivered in time for Christmas.
Also available are the console with Killzone: Shadow Fall and the console with Knack, both priced at £384.99.
Detail as below from Amazon:
Sony announced a range of PlayStation 4 console options available at launch in October, offering some fantastic titles and great money-saving bundles.
At Amazon.co.uk we have contacted customers in the order in which they placed their original PS4 standalone console pre-order, offering them the chance to choose from the different bundles available, or to stick with their original standalone console pre-order. We have now completed the selection process for customers who wish to switch their existing standalone console pre-order to one of these bundles.
As a result, the PS4 bundles listed below are now open for new pre-orders.
● Customers who cancel their pre-orders on the standalone PS4 console and place a new pre-order from the bundles below will not get their bundle for release day
● Customers who have already switched to a bundle and who cancel their pre-order and place a new pre-order from the bundles below will not get their bundle for release day
● Orders placed for the console bundles below from November 14 will receive their bundles after release day but before Christmas
Edit: Flubit are offering to beat this (they offered £423.54 for me when I tested this), though there's no specific indication of when they'd deliver for (aside from not before 29 November, clearly!).
