Nintendo has been hush-hush on any new, big Wii and Nintendo DS projects since July's Electronic Entertainment Expo, but if current rumors are to be believed, that radio silence won't be for much longer.
Word through various sources is that Nintendo is readying a press event in Japan for October 2nd or 3rd. While we have yet to receive confirmation of such event from our Nintendo of America sources, this rumor is strengthened by a two-day event scheduled by NOA for October 2nd and 3rd in the US.
No hints of what the company has planned have been revealed by NOA, but the timing of the Japanese event rumor ties in well with the Nintendo of America event. It's possible that a large-scope announcement or announcements will be made by Nintendo's Japanese branch and relayed to North American press during the scheduled event.
