I'm not sure if there's a set price for the new 75mm Biotar at this point. Various contribution levels net you various things, from being able to place an early order for the lens to the lens itself to the lens plus perks.
Looks like there'll be a new 58/2 Biotar as well.
The bokeh with the 75 can be subtle or wildly intense depending on aperture, focus distance, distance between subject and background (or foreground) and luminosity range within the frame. Something to be aware of in use, and also something to have fun with if you're so inclined.
The classic Zeiss Sonnars, and close copies & variants thereof, are among my all-time favorite lenses.
