Yea but he's not talking about the PS4 specifically.
I've always thought that basically DVI = VGA + HDMI, as in HDMI is basically the digital portion of DVI which has both (DVI-A that is). In fact it's more like Dual DVI = VGA + 2x HDMI.
Anyway so now it seems that there is also the possibility of analog video over HDMI, otherwise that passive cable would be useless. I still don't think that many HDMI devices would have analog output included. Laptops may have since they indeed need the compatibility with VGA projectors, but I don't see why the PS4 would have that. Having analog in the HDMI out needs a DAC and even though that's probably a 50 cent device it's still extra cost which basically nobody would use. Wiki states the PS4 has "HDMI (480p, 720p, 1080i, 1080p, and 4K for pictures and videos only". Methinks that if Sony would want to support analog video out, they'd just use standard RCA or S-Video or whatever the older consoles had.
