Nintendo may not have a main stage E3 press event in its plans this year, but that does not mean it won't have any interesting presentations.
Press have been receiving invitations to two developer discussion events, each scheduled to run for about 90 minutes. The first, planned for Tuesday, 10th June from 7-8:30 p.m. PST, will focus on the upcoming Super Smash Bros. games. Director Masahiro Sakurai is expected to be present.
The second event, scheduled for Wednesday, 11th June from 6-7:30 p.m. PST, is somewhat more mysterious. Nintendo has only revealed so far that this presentation will be on "a new game for 3DS."
