Apple was impacted by the holiday sales of the Kindle Fire and Nook much more than it expected; and likely the company feels that this is the only way that it can regain its stride with competitors. It is expected that the new iPad 3 will add a number of new features, including an 8 megapixel camera as well as a new updated high resolution screen.
It is anticipated that Apple will be hosting an event to make the announcement; but rumors of a MacWorld launch are false, according to our sources in the field.
