Considering the PS2 was a trojan horse for DVDs and the PS3 for blu-rays, it is baffling why Sony would forgo UHD in the new PS4 (maybe not the slim but at least the Pro). I mean, its a format that Sony as a whole is vested in, much like 4K televisions, with 4K support being a push for the reason WHY you would want a PS4 Pro.
This seems like a poor decision. They can spin it all they want about streaming, etc, but it was shortsighted and cost saving measures that had them travel this road. The fact that Microsoft, who bet on the failing format early last gen, is supporting UHDs and Sony isnt is crazy. Would the UHD drive have broke then bank on the Pro? I assume no if Microsoft can slot it in the Xbox One S.
Recent moves by Sony seem pretty poor and, as a Playstation fan and supporter, pretty disappointing. Ignoring the fact that Sony drops products almost immediately (the Move, the Vita...the last one really hurts), you recently have the PS+ price increase (which I think brings it to over XBL pricing, especially after MS dropped their price down to compete with Sony, not to mention the decline in benefit compared to last generation with regards to free games), you have the Slim which, unlike the Xbox One Slim, offers no real benefits over the current version other than a smaller case, and then the Pro which seems less of a warranted upgrade than the Scorpio (assuming the E3 announcement still holds true) and is lacking a UHD drive to boot. *shrugs* Maybe poor buzz and MS able to put up a better fight will push Sony? They seem to hit all cylinders last generation into the start of this one due to being behind the competition but now seem complacent.
