Announced from ABC News, Apple is going to release the 3rd iPad on either Feburary 2012 or April 2012.
Based on information I've gathered(so far), the iPad's new features will be
a replaced microphone
Siri(uncomfirmed)
Retnia Screen Display
thicker size
and many more items which are a bit edgy to place.
Upon the release, the iPad 2 will have a decreased price to compete with the Kindle Fire.
No more information that is worth saying is released.
