Personally this set is a little unimpressive/boring. It'll be interesting to see where they go from here cause the initial Mario sets were also lackluster.
I'm not sure if it's valid anymore (I am far from a brick aficionado but I have friends that are very into it), but the old rule of thumb says $0.10 per piece, which would put this at $250. $50 Nintendo tax doesn't seem out of the question, either.
