I do photoshop editing for a living and I'm not seeing much of anything in these photos that makes it jump out and scream fake. Gradients all seem legit, no obvious photoshopping. There's some sketchy noise around the PS4 logo, but other than that looks legit.
These console refreshes usually are an 'in-stores now' kind of deal. You don't want to announce a new console and not have it out for months; you're basically telling everyone not to buy your current console until it comes out.
I seem to remember the Xbox 360 E was available to order the day they announced it.
