It might actually be true that Apple is about to announce a new New iPad with the A6 processor, lightning port and IGZO display.
You can see it this way: the new iPad with the A5X processor was just an updated version of the iPad 2 released in March 2011. In March 2012, Apple wasn't able to deliver a proper updated iPad 3 (remember all those reports about IGZO technology being not available yet: now, Sharp announced their factories produce enough displays to be used by a large number of tech companies, such as Apple). So, they incorporated a Retina screen, the A5X processor and more RAM to run the higher resolution and a massive battery needed for it. But in fact the actual major update was the Retina display.
And - admit it - it has just never felt right how long it takes to charge the new iPad and how large its battery is (plus, Apple just has to update its new iPad with the lightning connector - otherwise, it would be weird having a new iPhone 5 and iPad Mini with that type of connector and the big brother of the latter still using the 30-pin connector - and while doing so, why not just update the processor and the screen?)
So, people, get ready for some sweet Apple announcements in a couple of weeks!
