You know what S&W is long overdue for? A polymer-frame Revolver. I know that some of you will boo me for speaking such heresy, but the fact of the matter is that polymer-framed Revolvers would be lighter in weight and less likely to develop stress fractures like their Scandium alloy frames, not to mention be substantially lower in cost.
You mean like the abomination that is the S&W M&P Bodyguard 38? No thank you. (Sorry -- nothing personal meant; but the BG 38 was loaded with problems).
On a more positive and fairer note - perhaps S&W have learned a lot from the BG 38 and will strike a home run with a 2.0 version.
