The title of this thread may very well be a mute point. It may as well read "Ruger #1 Past...".
I went to the Ruger website to see what the 2015 calibers are going to be and the only #1 listed is the Lipseys 45/70 distributer exclusive.
There are stll pictures of the light sporter, medium sporter, tropical, varmit and international on the website but no calibers listed.
