No it wouldn't. The bit(s) of kit that passes the signal still needs to support whatever copy protection/handshaking/etc is present in the sending/receiving devices. (Same thing happened with 3D.) So, even if I bought a new amp with 4K passthrough right this second, if it didn't have HDCP v2 it still wouldn't work with the cake tin anyway.
This raises a question about the PS4: if it does become another (or, outside of the US, the only
) means of Sony distributing their 4K movie content, then surely it'll also have this latest HDCP version? But HDCP v2 is not backwards compatible like v1, so I guess that Sony will also have to build in native v1 support so as not to alienate the millions upon millions of consumers whose displays won't do v2. No need to penalise the non-4K users for not having something that they wouldn't be using anyway!
There's no sign of a second HDMI for the audio/video split on the PS4 though, which makes a pretty big assumption that people's amps will be HDCP v2 compatible by then (never mind HDMI 2!). Legacy 5.1 audio support for the 4K content (over optical) becomes even more crucial, even if it is only lossy.
