Just grabbed the first part on DVD, as everyone's sold out of Blu-Rays, and I don't even own a functional BR player... plenty of third-party sellers on Amazon seem to have it in stock, whereas Amazon's got it marked as "shipping in 1-2 months" which likely means they are out of stock and hoping to get more, which might not happen.
I'd like to have the rest of it, but I suppose there's always sailing the seas for it.
