Don't be surprised if Nintendo actually makes some serious announcements tomorrow.It’s now common for me to wake up, flip on my 3DS, and view the ridiculous new Swapnote images my friends have scribbled in. I didn’t expect there to be a Swapnote from Nintendo of America president Reggie Fils-Aime telling me to pay attention to tomorrow.Nintendo’s been holding pretty regular “Nintendo Direct” events, basically mini press-conferences, since the launch of 3DS. It's where the company has been revealing dates, games and services.It’s probably not a coincidence the newest “Nintendo Direct” will also be taking place on the same day Sony officially launches the successor to the PSP, Vita. Some consumers already have their machines, having ordered specially priced “early adopter” bundles.Tomorrow's event takes place at 6:00 a.m. PST / 9:00 a.m. EST at www.nintendo.com/nintendo_direct.P.S. If you're not using Swapnote, you should. It's really neat!
