Does anyone know if there is anything particularly special about this release? Neither Amazon.com or tvshowsondvd.com seem to have specifics, but I LOVE the box art. Is it just a re-release of everything that has been released before?

Also, they are calling this an "unlimited" release...what does that mean?
