Toyota will probably take another stab at the Venza concept soon. But they are doing just fine with 4Runner which is midsize 5 seat and sells almost as fast as Toyota can ship them across the Pacific.
Subaru sells a midsize 2 row Outback. It is one of the biggest seller in the segment. Not sure what you are going on about nothing from Subaru.
VW is also working on a smaller Atlas with 5 seats.
