For no practical reason, I would prefer to see it be a .220 Swift AI without the semi-rim. Seems it would make more sense and be more in keeping with the apparent philosophy behind their other proprietary rounds (bigger, faster, badder, long-rangers.) It could make a sizzler of a varmint round and they might even develop a bullet in the 70 - 75 grain range specifically for pronghorn, deer, whatever...
I don't see where much of anything else mentioned as possibilities doesn't do much that's not already being done.
