I am having trouble seeing the justification (other than a reason for a new barrel) since I already own a 17HMR. Only difference I see is that the velocity is a little lower. Seems my 17 HMR will do everthing it will do plus some. They say the price will be lower (I heard $5.50 a box) but I have seen some 17 HMR advertised lately for $7.50, I do not shoot enough of them in a Contender to make a difference.
Now that new XTP load for the 17 HMR has my attention. That round can benefit from a less explosive bullet for some applications. Glad this post was here, I had not heard about the XTP version till I followed the link.
