I haven't seen anything for 2017, but two of their gravel bikes went through-axle in 2016 (Roker and one of the Willards I believe), so I would be very surprised if that feature didn't propagate to the Tamland for 2017.
I have a 16 Willard 1 (luv it), but always liked the Tamland in steel. Low rider fork mounts would be nice for 17. Kinda like jamis did with their upper renegade line for17 I would like to see the Tamland more bikepacking friendly.
Be careful with the Raleigh RXM. I bought the frameset to build up and it looks like it will be going back, with the support of my LBS. I had a set of WI CLD hubs built up into a really nice wheelset for the build, and the centerlock ring rests against the inside of the fork when mounted. In disbelief, I mounted a DT 350 wheelset from my 29er that has 6-bolt rotors, and there is about enough room between the bolts and inside of fork to pass a business card. It really bums me out since it was nearly exactly what I was looking for in a frameset.
