I dropped into my local GW today, and yes, was shown (on the site) the paint bundle. Here in Aussie it is $870, but the GW employee was quick to point out that it came with a free army case. I'm loathe to spend more than $20 on paints at one time, let alone almost nine hundred dollars.
They had some on show, with which you could test, and I must say, I do like them.
The white base (ceramic I believe) has total coverage when put over black, no more millions of coats.
The Dry ones have almost no moisture in them whatsoever, meaning no more streaky dry brushing.
The shades fill gaps, but don't coat higher areas very much.
The glazes will coat evenly, more being used to slightly change the colour of the surface, doesn't pool in gaps so much like shades do.
The textures are pretty self evident.
Nothing to buy in store, was told would be on sale in store on the 7th of April.
