The rumoured price is 1500 USD which is about 500 more than my interest level. At that price why not just buy a 200 when they come up as they usually come up in the 1500-2k range.
They mention it is a "improved" version of the 200. Improved probably means cheaper, obviously newer and more stable parts which I'm less interested in.
Apparently they will be built per order so you will probably have to throw down half or all the price of it to play around with one.
