It seemed to have had a lot of hype before it came out, but since it's been released it's had very little publicity. They needed to capitalise on the initial interest, there failing to do so will probably be the death of the cartridge.
That and the only gun it's chambered in is the Savage Bmag, which seems to be a very average gun. Had it come out in a CZ I think it would've been a big competitor against 17hmr. But since it failed there too, and 17hmr has a very very strong hold in the shooting world, I don't think it'll last.
The release of the 17 Hornady Hornet probably upset things a lot too. As 22 Hornet based cartridges still have had a decent group of followers, and 17hmr being very popular, there really didn't need to be anything in between.
Too give another perspective on the second point, in New Zealand I have seen no sign at all of 17wsm, but I have seen 17HH ammo for sales, as well as in both NZ and British forums and groups of shooters, I've heard the 17HH mentioned a few times, but none whatsoever of 17wsm. I think it'll go the same place as 223wssm and 25wssm.
