In the UK (& AUS + NZ) you'll be able to get it in hardback published by Voyager. Pre-order here, or here for free worldwide delivery!
In the UK we have a new cover!
The artwork is by the late great Kimberly Kincaid who died unexpectedly and far too soon. She created the image just because she was inspired by the books and I'm very glad that Voyager were able to agree terms with her estate in order to use it on the cover.
You won't find Road Brothers in paper format outside the UK/AUS/NZ but the compensation is that in those locations where it isn't sold in hardback I will be able to sell a separate version with just the additional stories for the difference in price between the new version and the old version ($1) so that nobody who bought the old version will need to pay more than those buying the new version to read the same set of stories!
