I would have expected that some web site would have disassembled a PS4 and provided detailed photos of the components being used, including the specific HDMI parts (this was done for the PS3, but I haven't seen it for the PS4). I have seen some teardown videos for the PS4, but haven't seen one that lets you identify the specific HDMI chips being used. It is likely Sony is using HDMI chips from Silicon Image (as did the PS3) that will have a part number like this: Sil9xxx. (e.g., Sil9136). So the bottom lines seems to be there was some pre-release indications from at least one Sony representative that the PS4 would have a HDMI 2.0 port, we really need to confirm this with the production units. I guess the bigger question is, even if the PS4 has the essential hardware, will Sony invest their resources to make the PS4 capable of playing UHD Blu-ray discs.
I think that just like they used the PS3 was a way to promote bluray, they could use the PS4 to promote UHD Blu-ray, provided they had the foresight to make the hardware compatible (even if in a minimal way).
I'm not saying they did, or indeed that they will be able to invest the resources to develop the software to handle this, but if it was part of their plan it could happen. They have an interest in selling 4K displays (TVs and projectors) and giving "for free" the least expensive part of the equation (the source/player) would allow them to sell the content (movies) and the displays (as well as a few AVRs), where their margin is huge.
Not a bad business plan, if 1) they thought about it and 2) are still able to implement it given their dire financial state.
My only point here is that unless there is proof that the PS4 can't handle bluray 4K because the hardware isn't up to scratch, I don't think we should rule the possibility out.
I don't have a PS4, don't plan to get one and have no vested interest in Sony either, so I'm entirely neutral
