" Apparently there'll be an even longer cut on DVD later of the whole 3-hour epsidode (parts 1 and 2), and of one or two other Season 4.5 episodes."
Yup, not surprised. It wouldn't be BSG without an excessive quantity of DVD releases. First there will be an extended finale cut DVD, like the extended Razor DVD, then it will come included on the 4.5 DVD release, like the extended Razor. For BSG fans, patience definitely pays off.
