Let me put it this way.
There's no guarantee that its a real product and not just a rumor.
And even if its a real product, there's no guarantee that its coming to the states.
And even if its coming to the states, there's no guarantee that its coming to AT&T.
And even if its coming to AT&T, there's no guarantee that its coming as soon as its announced and not several months later.
And even then, there's no guarantee that its not going to cost an arm and a leg.
So you can wait if you want to, but it might be a long wait with no good result in the end.
