The Verge:
Sony's decision to not announce the price or a firm shipping date for the PlayStation 4 will no doubt give the company room to manoeuvre should it need to respond to any gaming announcements from Microsoft.
Gizmodo:
Sony has revamped its user interface for the new video games console
As the hours of demos and introductions dragged on, it became increasingly obvious that we weren't actually going to see the PlayStation 4. Sony either isn't ready for primetime, or Sony thinks the best way to get us interested is to play hard to get.
Wired:
Talk is the cheapest thing there is. And that's basically what Sony did today: It espoused a philosophy, said the names of a lot of popular games, but didn't give us any real, concrete information in an age where it's more important than ever.
Computer and Video Games:
Sony is not only responding to a world disrupted by Apple, that will only continue to fragment, but is trying to see past it; to carve its own niche. It's no small step that PS4 is being developed out of the west, and not Japan - yet even more surprising to learn that work began on it five years ago.
Spong:
Most exciting is the share button. The PS4, we're told, will sneakily and transparently monitor and buffer our last 15 minutes of gameplay. This will be a boon to all those who think there is not enough inane video drivel on YouTube.
Techcrunch:
A new Killzone game was among the exclusive software titles unveiled at the event
What was missing from Sony was a discussion of anything that could've made it a more broadly appealing device. It (and we, as potential customers) needed way more than a falling back on graphics, eye candy and tech demos, which may have served the gaming industry well in the past, but which have done nothing to stem the rising tide of mobile platforms like iOS and Android.
Stuff:
The PS4 looks to be a confident riposte to the Nintendo Wii U, with an array of social gaming features that look set to - potentially - enthral and irritate in equal measure. Microsoft, the ball's in your court.
Cnet:
The PS4 looks like it's long on promises and big-picture dreaming, but currently short on clear, concrete reasons why anyone would be tempted to buy one.
New York Times:
New features cannot hide the fact that PlayStation 4 is still a console, a way of playing games on compact discs that was cool when cellphones were not smart.
Hab ja nur 5 Meter weg gesessen und hab extra geschaut, was er so drückt. Und das passte schon. Aber trotzdem gute Frage, ich schau mal wie ich die mit einbaue.
