I was going to mention that the rumor of a M2.0 is not new but Shield9mm beat me to it. I read another article about it back in August and postponed my purchase. That lasted until November then I sprung for Shield 9mm anyway while it was on sale. It still wasn't known when they would appear and my pockets were on fire.
I agree with Ditto1958 in that the finish is already great. I don't think I'd buy another simply for a trigger update. Mine works fine although it's at ~6.5lbs. (after some polishing). It was at 7+. I hope they do something with the slide guides, especially the rears. They seem to show more wear than the fronts. I guess from recoil pressure. Perhaps longer guides would help.
It's like a new car. They throw in a few extra options, change the light bezels and call it new. I'm saving for a new Victory 22 now so it would take quite an update on M2.0 to make me think of buying another.
