In this case I believe that the delay is 100% due to Vizio. They are notorious for launching their TVs and other products late. If you do a search of Vizio forums you'll see tons of posts asking where new TVs are that were supposed to be launched months/quarters ago. And this isn't new, it's been going on for years. So while SIO certainly dropped the ball getting 3DGO ready, the slow and gradual launch appears to be Vizio's fault. But at least we're getting there, and we know at least SOME Vizio 3DTVs have 3DGO on them. But it's another reason that getting other CEs on board soon would be a good idea.
