I don't care too much, 'cause I haven't played with LEGO in years, but Zelda would be cool, provided the DON'T EVEN CONSIDER MAKING A GAME.
Personally I think if Lego were to acquire a Zelda license a Lego Zelda game would be pretty cool, but I doubt such a thing would happen. Lego has not had many video game licenses, but if they did I'd doubt a "game of the theme of the game" would be made. The last thing the content owners would want is for Lego to make a game of their property that would directly compete with the property itself. I imagine this conundrum applies less with things like the Lego Star Wars TV specials, since Star Wars is a large and established franchise, the Lego specials are tonally different, and TV and film are just a medium with more room for variety without having various works have to necessarily compete head to head.
