Why do we still need IPv4 when we are migrating to IPv6...

IIRC this was for communication between a dual-stacked XB1 and an
IPv4-only XB1. It's impossible to use IPv6 for that, because IPv4 is
the lowest common denominator. The XB1 is simply using Teredo to tunnel
P2P traffic over IPv4.

Is there any known problems related to IPv6 communication between two
XB1s that both have native IPv6 access?

No, I just exchanged some e-mails with an SCE guy back in October. He

«As for the PS4, the hardware was designed with IPv6 in mind and they
are planning to enable IPv6 at some point. (It is just a firmware
thing.) Initially we were told that the PS4 would launch with IPv6, but
in the end I think they were just so busy getting all the other stuff
done that they decided to wait on implementing IPv6 on it.  I know that
they are still planning on implementing it, but unfortunately no one
has shared any dates with me.»

Hopefully it'll come soon.
