well, at this point, ill have to chalk that up to his being mistaken
i can't find any relating media on it being a hoax (in addition to searching the net, i even scoured the foxnews.com site, with no such article -- rather, a similar press release for the design that i've found elsewhere).
further, i find more and more updates and coverate of the site and the design, daily,
on reliable news sources, like yahoo (which uses associated press stuff, mostly) and cnn and msnbc.
in addition to all that, the actual site (wtc2002.com) is chock-full of media and articles and press releases and speaches and documented events. fully 3d rendered animations and designs, complete (and sound!) architectural layouts. plus, the designer, turner, is a former trader who lost quite a few of his closest friends.
so if its a hoax -- thats frickin amazing and disturbing
i'll keep looking for evidence to the contrary, however... im fairly certain its no hoax.
