Mark your calendar for March 2nd. Apple is hosting a media event in San Francisco next Wednesday, and with all of the rumors that have been going on for the past couple of months, we expect it is for one thing. The iPad 2 announcement.

Apple Insider reports: “Apple on Wednesday sent out official invitations for a media event next week on March 2 in San Francisco, presumably to show off its second-generation iPad. According to The Loop, Apple sent out invitations to the media on Wednesday. The event will be held as usual at the Yerba Buena Center for the Arts in San Francisco.”

Maybe Blackberry maker RIM knew about this, as the company is showing off its PlayBook tablet to the media in New York on Tuesday March 1st.
