Hi Marcos,
The information that you have is correct as far as I know. Last I heard PBS had not yet settled on a final air date (and it hadn't been determined whether it would air on "national" PBS time or individually at various times on local affiliates).
That said, I have it on good authority that the 90-minute finished product is of excellent quality and will be a huge asset for the FIRST community for years to come
