Last I heard, in December when I bought my GCL, was they were first delayed to January, then February, then they switched to Feb/"in development", and now you're saying March. It's winter, so if I were you I would just order the weathertechs. I did. They fit well, just be sure to order the correct third row mat for your vehicle (some are bench second row, some are buckets with a center console, and some are buckets without a center console. I'm pleased with the set they sent me.
Also, for anyone interested in cargo protection,
this company makes a really good-looking option that covers the seat backs for cargo use. It's a better solution than the cargo mats given how the third row seats fold. They also make side liner protection for the cargo area too, all in various colors and patterns, with custom stitching colors too.
