Following up on some teasing comments from a few days ago, Nintendo CEO Satoru Iwata has shown the first screenshots of the upcoming Super Mario title for the Nintendo 3DS during his keynote address at the annual Game Developers Conference.  The Super Mario Galaxy team is hard at work on the new game that may or may not feature the return of the raccoon tail flight ability from Super Mario Bros. 3 if a certain temporary logo has anything to say about it.  More details will be announced at E3 in June.
