Satoru Iwata took to the stage of Nintendo’s E3 press conference this year to talk about the Wii Vitality Sensor, which was met with mixed reactions. When asked about the presentation as a whole however, Iwata didn’t seem too pleased.

“It is apparent that we could not fully convey the charm of our products [at E3]. In the past, Wii Sports and Wii Fit were naturally able to convey their appeal on stage. [...] This year, however, with the New Super Mario Bros. Wii, four people lined up with Wii Remotes was not a scene that no one had ever seen. Those who actually had the chance to play understood how the game would change with four people playing simultaneously, but we could not address that fun sentiment at the media briefing.”

This wouldn’t be the first demonstration for a Wii game that didn’t exactly go the way Nintendo wanted — last year’s infamous display of Wii Music became something of a joke around the internet. While Mario Bros Wii wasn’t met with anywhere near as negative a reaction, it didn’t exactly make the headlines either. Even Nintendo’s own announcements of Super Mario Galaxy 2 and Metroid Other M overshadowed the title.

Still, what doesn’t kill you can only make you stronger, and it sounds like Iwata’s all fired up for E3 2010. “Now we strongly feel that we need to look into finding a better way to demonstrate the products’ appeal better at E3 in these times where more people are watching it online via web cast not only in the U.S. but all around the world. In that sense, we learned many lessons from this year’s E3 show.”

Will Nintendo get it right next E3 then? It seems like the company is going to be moving further away from 2008’s briefing, and that can only be a good thing.
