Nintendo is silent for a reason

And they have: NSMBU and Nintendoland are leaps and bounds ahead of what was there for 3DS launch (Pilotwings and Nintencats)

It's not quite helping the sales, but it is definitely better.

I think Nintendoland is undermined by the amusement park facade and NSMBU is very similar to NSMB 2.  I hope they have something to announce @ or prior to E3, the word of mouth is not there, in fact kids that played over at our house (Nintendoland, NSMB U, Superscribblenauts), had enough just after a few levels and wanted to play something else.
