Thanks all! I am keeping an eye on LinerX as well, but they don't have an ETA mentioned anywhere.
Has anyone tried the old-style (i.e. without anchor post) all-season mats on top of the anchored carpet mats that came with the car? I was unsure if it will stay put or will slide around. I read some messages earlier about regular mats sliding around, but it was in the context of using regular all-season mats on models without anchor posts.
