I can tell you that the S&W business model with the M&P has not changed since it's inception: Come out with a Gen 1 with a manual safety, then come out with a Gen 1 with no manual safety, then come out with a Gen 1 Performance Center with a manual safety, then come out with a Gen 1 Performance Center with no manual safety, then come out with a Gen 2 with a manual safety, then come out with a Gen 2 with no manual safety, etc., etc., etc.

Let's not forget that the M2.0 is really just a tweaked M1.0 with some cosmetic upgrades.
