Technically, the proper phrasing would be that the SAR is on the way out (even though as others pointed out, it will still be supported just no new ones made). The X95 is still a "Tavor". Much in the same way that the M16 and M4 are both different generations of the AR15, but have separate model designations.
Many people within the community wondered why IWI even bothered with the SAR, since the X95 had already been developed and proven before they ventured into the US market. This would be the equivalent of Colt or Armalite starting up in some other country by offering them carry handles and non-improved feed ramps, or Glock selling Gen1 pistols - with the full intention of offering the already developed upgraded models only a few years later. Sure, some nostalgic people would love them, but for the most part, they have already been superseded.
