the street price is going to be a lot lower, and the MSRP may also come down once it's on the market. if the selling price comes down to $4000 or so, they will sell some, if not a lot. and inflation-adjusted, $8000 is the same price as the Yamaha B-1 VFET was in 1974.
this is a statement piece, remember. none of Yamaha's main competitors are making anything like this, at least as far as i know. i don't understand why more people aren't glad that they would do this. although if you're thinking vintage, it IS going after it's traditional competitors: Accuphase, Luxman, and Marantz. pricewise, they aren't completely out of line even at $8k. only time and ears will tell how well they do with this.
