@diego, why do you think nintendo won't show FE, it's already released in Japan for a long time, feb this year actually. Also according to Wikipedia the US release date is November this year.
As for E3, a spokesperson of Nintendo Germany has claimed Mario Kart Wii will be released this year, and more information will follow at E3. Unfortunetaly there isn't any claims of this on the english wikipedia site, just the dutch one:
http://nl.wikipedia.org/wiki/Mario_Kart_Wii
I highly doubt this information to be true, but I do think E3 will tell us more about Mario Kart Wii. Here's a translation of what the site says:
Mario Kart Wii is the tentative title for the latest part in the Mario Kart series and was announced for the Wii. According to Patrick Nagel (Marketing manager for Nintendo Germany) will there be information available during the E3 Media and Business Summit in Santa Monica on 11 July 2007. He also claims that Mario Kart Wii will be available before 2008 in Japan, North-America and Europe.
