This is going to be an important e3 for the Zelda franchise.
From the sales history, there's hits like Ocarina of Time, and Twilight Princess, with roughly 8 million units sold (7.6m for Ocarina, 8.1m for Twilight), but sales have been on the decline as Nintendo ignores a large portion of the Zelda series' original fanbase.
Wind Waker was a very polarizing game. I remember how off-putting the art style was to many of my friends when the game released, and while it sold well (5 million), it sold significantly worse than Ocarina of Time did. I feel that Wind Waker's poor performance, and shift in style, helped contribute to Nintendo losing market share among core gamers during the GC life-cycle.
Twilight princess arrived to enthusiastic cheers at it's e3 debut, as it represented the series return to it's core audience. The game sold much stronger than Wind Waker, and helped build positive momentum early in the Wii's life-cycle.
By the time Skyward Sword arrived, Nintendo had already seemed to have completely abandoned core gamers, and had devolved to just releasing cartoon-graphic party games. Despite many Zelda fans complaining about the "waggle" nonsense in the Wii version of Twilight princess, they went on to shove BS gimmicks down gamers' throats in SS, and made motion controls a huge focus. Despite a large portion of Zelda fans disliking Wind Waker's art style, Skyward Sword was released with a very young child friendly aesthetic, once again, only this time featuring less chibi characters and more water color. The game went on to be the worst performing 3D Zelda game ever.
The ONLY thing I want to see out of Nintendo this e3, is a legitimate Zelda game. No stupid art style. No gimmick controls. No 10 year old version of Link.
Despite my reasonable request, I'm holding out no optimism, and pretty much anticipate Nintendo will just continue to alienate the older Zelda fans, and release Minish Cap Wii U or some stupid nonsense. *sigh*
