Well given that it takes at least 3yrs to safely develop anything close to ffxi orginal.
You got around that time for ffxi to become part of history.
Without a doubt there is a sucessor in the works, but given the timing of 360, and ps3, they will put effort into driving FFxi till then.
And EQ1 had its unofficial RIP long ago. People can still play it, but ever since EQ2, you can see no one really puts much focus on it besides keeping it running.
FFxi at this point without any sucessor, SE will still actively pour resources into it, as we just seen from oct update
