Nothing is over for XMPP until a better open alternative comes out. If Google see their Hangouts as a way forward, let them open the protocol and pull it through IETF to make it a standard. Oh, they are too selfish to do it? So they can get lost then, it's not an XMPP replacement.
No one else is eager to do anything like that as well, so XMPP remains the only candidate at present.
