Hmmm, maybe, I guess so. It would have to be done really well. I hope the DWP get involved somehow. They turned adventure map playthroughs into an art form practically. I'd think they'd use a modified version of the default texturepack, though maybe a higher-res version more suitable for a big screen, and maybe shaders as well. Of course, that's all contingent on if they end up doing it all in-engine. For all we know, it could be 3D animation made to look like Minecraft.
