PlayStation Europe has already rolled out the PS4 1.51 firmware update, so continental PS4 owners-to-be can prepared extra early for the console's launch on November 29.
As per the 1.5 update that arrived ahead of the North American launch, Europeans can download the 308MB update and store it on a USB stick. When their PS4s (hopefully) arrive on Friday, it's just a matter of copying the file from the USB stick across to the console - and given the strain the PlayStation Network endured last time and the features conferred by the update, it's probably the wise thing to do.
