The rumor mill is already pretty well churning with the possibilities of the new tablet. Given the phrase on the invite, "We have something you really have to see," most outlets are assuming the iPad will see a bump in screen resolution, which would be welcome.

Even odder, they make a fairly convincing argument that Apple is eliminating the home button in place of some kind of touch button.
