But the third-generation iPad is just called that, 'iPad'. It's only referred to by Apple as 'new iPad' in contexts where its new features are described, or to distinguish it from the previous iPad, such as in the online store.
Have you forgotten how much everyone hated the iPad name when it was first announced? "New iPad" only sounds good because people have come to the love the iPad.
Remember when Nintendo anounced the name "Wii"? Everyone was ridiculing it and web cartoonists had a productive work day. And then everybody moved on and today it is just normal.
