Satoru Iwata has said that there are plenty more unannounced Wii U games that could've been shown at E3. He noted that if they were shown too early, there would be too long a gap between the announcement and the actual release of the game, therefore they waited.
Honestly, I would've preferred if they'd at least given us an idea of one or two of the other games they're developing, I was really disappointed by the E3 Nintendo Direct, and there was a lot they still had that could've been shown off. They even said the Zelda Wii U game could've been shown at E3 too.
