Currently, Samsung is offering two models of The Wall, or rather the individual panels that make up The Wall, the IW008J and the IW008R. While Samsung doesn't list prices for these panels online, other resellers are listing the modules for $16 to $23 thousand dollars each.

These individual modules measure 31.75 x 17.86 inches, but have an individual resolution of 960 x 540 pixels. In order to enjoy the same 3840 x 2160 resolution you'll get on a standard 4K TV, you'll need to buy 16 of these panels, to set up in a 4 x 4 configuration that measures 146 inches diagonally.

I'm more interested in what it's going to cost in 5 years.
