My guess is that Remington will continue to load their SAUMs for a couple more years as a face-saving device, but it seems as if that line is moribund. I don't know yet if they're going to chamber WSMs, but we'll find out in a week at the SHOT Show. In short, I don't know much, but I have opinions on nearly everything.
You don't have to wait for the SHOT show. The 700 SPS is being chambered in .300 WSM. It's been on their website for weeks.
