The softtail that you are looking for was a bit of an evolutionary dead-end in the MTB world.

There may or may not be a manufacturer still making them, but they are not at all mainstream.

This seems to have been replaced by the category of X-C short travel full suspension bike like the Trek Top Fuel, and a couple others. Though this is also not a big category in the industry.

Hope you find what you are looking for.
