So now we have a date. According to the iMore website, its sources are saying that the iPad 3 will be introduced on March 7. This is in sync with the earlier report by a usually reliable website that the event would be the first week in March. And March 7 is a Wednesday — the day that Apple has often used to launch a new product. Plus, there was the recent report of a major retailer discounting the iPad 2, which is usually in indication of clearing out stock in anticipation of a new model.
iMore's sources also said that not only would the iPad 3 have a 2048 × 1536 retina display, but also an A6 quad-core processor. And it gets better. No less than the Wall Street Journal reported yesterday that the new iPad would be compatible with Verizon's and AT&T's 4G LTE networks for speedy data transfer. A faster processor, faster network speeds, and a retina display — this iPad is sounding like a winner. An open question is whether the iPad 3's LTE capability would be compatible with other networks. You can read a discussion of this issue in another article on iMore.
In addition, the Wall Street Journal reported today in a separate article that Apple has shown designs of an 8-inch iPad to suppliers in Asia, suggesting that it's also considering selling a smaller model in order to broaden the tablet's appeal. If it's true, it's still in the idea stage, so we wouldn't be seeing an 8-inch iPad anytime soon.
The Wall Street Journal has also posted a video that discusses Apple's consideration of an 8-inch iPad.
