Kinda funny to call it an open invitation while Sony and Nintendo have been open to it for a couple of years already. It's called RSVP not invitation!
But now all 3 are open to it, maybe it will finally happen?
The way they word it it's left up to developers. So I guess psn xbox live cross chat and friends is not part of the deal. More like, devs are allowed to figure out how to combine different players themselves.
