Google Zelda U Breakdown and you'll get a crapton of hits.
I believe there was one on gaf as well tat had a screenshot of the trailer and highlighted all the major geographic features. They used the location of death mountain relative to a town to claim it was castle town before the castle and argued that by extension it was an earlier entry in the series' timeline.
They did a good job, convinced me that it seemed like it was an early installment, which is what I claimed.
