He then backtracked by by saying it's still possible if the track is ready, and that "If they can get it completed and confirm to us it will be done, for sure, they'll be on the calendar."

This month Sebastian Vettel drove the course and declared it "nowhere near ready," but that's to be expected since the race is a year away.
The Grand Prix of America has as much time as time to get a street circuit prepared as Austin did to get a dedicated track done, and so far, the GPoA hasn't suffered any of the funding and construction snafus that plagued Austin. We don't know what Ecclestone knows, but he doubted Austin's prospects as well and here they are, so we'll keep the faith in New Jersey.
