Consumers watching this show do not give a crap about Nintendo, period.
I think the whole thing is a demographic mismatch. Nothing they could show would rouse the interest of anyone who was not specifically watching for it.
I see your point, but I do think Zelda still is pretty viable in North America for a percentage of gamers who will be watching. It isn't COD, but I think it has a lot more potential than another 2D platformer.
