I like the new design. Looks futuristic, but i do agree it might not blend well with the rest of the buildings. Oh well, people would get used to it.
About the whole build the building or build a memorial instead, why not just have the new building be named WTC Memorial Building. Alright, that was a crappy name but still, maybe something along that line. Then have a statue outside of the old WTC towers with a nice gold tribute sign by it. Meh, that\'s what i think.
