The icons are a bit too close to be in landscape mode. I think it won't have a home button! Apples always hated buttons. I can't wait, already had asked off for the 7th a week ago and will be lining up on release day to be first!
Not to give in to TOO much speculation, but, this particular iPad also has Maps, Calender AND the Keynotes app on the dock... Not the typical apps you would throw down there. Possibly they have it in landscape, and just have the dock stacked full... Hence the closer than normal icons.
Just pure speculation.
BUT, if it truly doesn't have the home button anymore, that would definitely tie in with the "And touch" line at the end, there... Possibly hinting at a touch sensitive bezel?
Again, just pure speculation...
With that said, I would rather have home button. Lol.
