Look closely again at the invite apple sent out.Gizmodo are saying that they feel the picture is of the iPad 3 in actual portrait mode which would mean Apple are trying to get us talking about the possibility of NO physical home button on iPad 3. This would make a whole lot of sense especially since the introduction of multitasking gestures with iOS 5.1. I know i use the home button alot less since it was introduced.

Here is their reasoning via Gizmodo

Apple just flashed their new iPad 3 on theirWednesday 7 event invite. You can clearly see the new Retina display in all its glory. Compare the top (invitation) to the bottom (a photo of iPad 2).

The top has a lot more definition. It’s clear on the typography in the Wednesday, the spacing in relation to the icon and the edges of the icon itself.

Not only that, but there seems to be NO home button, which explains the mention of the “And touch.” in their invitation. How do we know? First, the photo they are showing is on portrait mode. You can’t achieve that icon spacing in the landscape mode (which is the only explanation for the lack of home button). Moreover, the icon falls right onto the same water drop that the current iPad 2 falls while in portrait mode. It’s clearly a photo of the iPad in portrait mode. And there’s no button to be seen.
