This will be the official one (skip to 20 seconds), or part of it, which could be for the quick resume if the console is left on sleep, which could mean if the console is turned off the initial start up could be different.
None of those concept start-ups would be anywhere close to the actual PS4 start-up, we all know Sony goes for subtle and elegant as oppose to typical *WOW-BANG-POP* like a certain 'other' console manufacture tends to do.
