The revision of the PlayStation 4 hasn't even been officially announced, but that hasn't stopped people from buying, unboxing, playing with, and reviewing the console already.
Let's Play Video Games has already gotten their hands on a 500GB model of the console, noting that there is no advertising or packaging acknowledging that this is a "slim" or smaller version of the existing PS4.
As seen in the video below, the new revision doesn't have an optical audio port (which most don't use). There's also nothing particularly special about the revision besides an overall shrink. There's no added 4K functionality, although removing and installing a hard drive is a hell of a lot easier now.
I'd seen some scattered reports on social media that the PS4 Slim runs a lot cooler and quieter than its predecessor, which is more or less what you want to see from a hardware refresh.
In the longer written review, Let's Play Video Games also talked a bit about the redesigned DualShock 4. Not much has changed, save for one thing that certain gamers might find very useful:
What is perhaps more interesting about the new controller model is that, when connected to a PS4 Slim or a regular model PS4, it transfers data entirely over wired connection rather than wireless. While this may seem minor, this allows a more frame-precise reaction time than wireless play, which will be incredibly useful for games like Street Fighter V. It’s a minor difference, but it’s a slightly tighter response which may make a difference to some players.
I'd still like to see Sony update the firmware so that it was smart enough to know when you've plugged in a LAN cable. But one step at a time.
