And indeed Nintendo knows this. The series' daddy, Shigeru Miyamoto, was quoted as saying: "[Twilight Princess] will be, without a doubt, the last Zelda game [in the series] as you know it in its present form," back in 2005. That could mean Nintendo already has a radical Zelda makeover on the cards.
Rumour has it that the next Zelda game for Wii is already in development, and Zelda director Eiji Aonuma has already expressed his wish to inject a greater focus on motion control into the next Zelda Wii game. Great things could be ahead for Zelda fans.
We think if Nintendo is to strike the right balance between changing Zelda enough to refresh the franchise and keeping enough of its traditions so as to maintain its heritage and please loyal fans, it needs only to look at its chubby mascot: Mario.
With every Mario game that comes along, Nintendo tries to do something inventive, unique and pioneering. Think of the leaps in gameplay from Super Mario Bros. to Super Mario Bros. 3., or from Super Mario World to Super Mario 64. And now from Super Mario 64 (and the slightly less hailed Mario Sunshine) to the upcoming SM Galaxy - which looks absolutely stunning.
If Mario can do it, so too can Link. It's just going to take some careful thought and a lot of balls.
