While market experts yet have to reach a consensus about the probable arrival date of iPad 3, but the rumors are not going to stop
anytime. The latest rumors now suggest that Apple may decide to equip its next generation tablet with quad core processor. While it had already been speculated that the new iPad would come with faster processor, the use of quad core processor is a new rumor.
It is also being speculated that iPad 3 would support the use of 4G speeds. No matter how much we would like to believe this rumor, but it seems highly unlikely that iPad would get 4G speed, while iPhone is still running on 3G. Rumors also did not address the issue whether such upcoming iPad would run on 4G channels of both AT&T and Verizon or not.
Deployment of 4G is going to have many other implications as well. Though quite unlikely, but Apple may decide to provide 4G speed to tablets first, owing to their larger batteries. Bloomberg also said that iPad is better suited to meet the requirements of 4G than iPhone is.
There are already several rumors suggesting that iPad3 will have superior resolution display akin to 'retina' display.
