Their demise had been announced in 2012. Perhaps S&W changed their mind. You can search the boards here, there was some discussion about it at the time.
I looked back on those threads, and the discussions were about the SD9/SD40, which indeed have been discontinued. In their place, S&W now makes the SD9VE/SD40VE.
Having owned a SD9, and now owning a SD9VE and a SD40VE, I think the trigger is slightly better on the VE models. The rear sight is plastic, and the front sight isn't a night sight. The slide is stainless, rather than melonite...other than those, I can't recall any differences between the SD and the SDVE. Anyone?
