First, don't expect the G to go back to a caliber they rejected. .308 ain't gonna happen,
Second don't expect the choice to make sense, it's not being picked by troops, it's being picked by Congress.
Third don't expect simple, they will cram on grenade launchers, smart technology, whistles, bells, and lights
Fourth,don't expect it to actually be BETTER, chances are it will just be different.
