Alone are better than the last 2-3 Nintendo press events. We've seen basically nothing on any of these games outside of X.
There's also the Retro Studios game which we haven't seen anything on.
And even games that are supposed to be out in a few months ... haven't seen anything new on The Wonderful 101 in ages for example.
That's why I find this a little bizarre ... Nintendo easily could have their best E3 press event this year by a mile, they definitely have stock piled the content and kept it secret.
