Apple announcing iPad 3 in the first week of March?

Is the long, treacherous wait for the iPad 3 nearly at an end? That's what anonymous sources tell All Things D. The site caught wind that an Apple event next month will host the announcement of the company's latest tablet. The event is said to be slated for the first week of March at that popular Apple haunt, the Yerba Buena Center for the Arts in San Francisco -- and seeing as how last year's event was held on March 2nd, that timing doesn't seem all that crazy. As for an actual release date, sources are not sure.
