The mysterious iPad 2 has yet to be released and may stay that way. According to sources instead of getting an iPad 2 announcement in March we may have to wait until June.

The iPad 2 was expected to be announced in early January, when that did not happen rumors started that it would be released in March by the Wall Street Journal. Unfortunately, nothing has been confirmed just yet.
In addition there has also been iPad 3 rumors, but they are not anything major right now and should not be taking seriously.
