Would be super dandy if it included all prior data for the FFXI install and follow-up expansions, regardless of whether or not the disc comes with an all-in-one serial key for it.

Just would be nice not having to backup of FFXI on my external drive just so I don't have to go through 4 FFXI discs, 2 CoP CDs, 1 ToA DVD, and 1 WoTG DVD, and then hours and hours of downloading patch data if I were to reinstall from scratch on a new rig.

Would also make the 360 release more viable, particular if it did come with an all-in-one key as new players could hop on without having to hunt the now-rare copies of either the Vana'diel 2008 collection, or the "Ultimate Collection" release.
