Why is the simplest question to ask. The 4th Gen iPad got the A6X right? Still a hot and great processor running on an OS that is very tight and light weight from a resource standpoint.
This sounds like a rumor created by the competition to try and stop prospective buyers from committing.
As I said..it will be a year since Ipad 3 come March.
Ignore Ipad 4 for now..
Ipad mini is nicer, it's lighter..I would almost guarantee Apple will put a 9.7" tablet out in March which looks like the Ipad mini.
Believe it now. Ipad 2/3 owners may wish to start saving..
