National Geographic is turning away from HD DVD and moving to Blu-ray only distribution, beginning with the release of "Sharkwater" in April. It's not a surprising move, as National Geographic is distributed by Warner; this leaves BBC as the last holdout from the Warner family to declare its love for Blu-ray. As excited as we'd like to get about a flood of National Geographic releases (they do have some great content!), the track record for the golden rectangle brand is pretty poor: the "Arctic Tale" special was in HD DVD and "Relentless Enemies" was available in both HD formats. Plus, April is so far away in format war time! Still, here's to hoping that expert assurances that an end to the format war is at hand will spur National Geographic to make with the HD releases!
