The PS4 Slim also has B/G/N/AC Wi-fi, so as far as wireless standards go, it sounds like Sony are all set.
As @shortmaneighty2 is confirming on Twitter (via NeoGAF), the PS4 Slim will indeed be supporting 5GHz wireless range.
The PlayStation 4 Slim is scheduled to be revealed, and then further go on sale immediately after, Sony’s PlayStation Meeting in early September.
This should come as great news to 40 million PS4 owners, who have been tormented and tortured by the PlayStation 4’s simply awful wireless capability so far.
