That's the same boat I'm in... interested, but awaiting available platforms and some actual case dimensions. I had also been interested in 350 Legend when it was first announced until I saw the stupid rebated head and oddball bullets. That promptly killed every ounce of my enthusiasm on that one.

If this ends up being from a from a standard family case with a .357/.358 bullet offered in a Henry lever or a single shot, I may hop on the bandwagon.
