My opinion ought not count for much since I'm a lurker on this board and not a contributor, but I'd vote for an AVCHD and MKV of Version 2.1 now. (I personally prefer the AVCHD format, since, when burned onto a Blu-ray disc, is more broadly compatible with Blu-ray players than MKV – but that’s neither here nor there). The Blu-ray seems to be the definitive release, the signature edition, the culmination of all of Harmy's blood, sweat, and tears. (Not to diminish the importance of all the crowd-sourced help given by folks on this board.) As such, Harmy ought to have the time to do it to his "complete satisfaction.” And if that means more time to get all the elements just right, and more time to perhaps create a cohesive unity across the trilogy, I personally am okay with that – it seems that Harmy deserves to have a final edition that he’s 100% proud of. Just my two cents.
