Does anyone know when The Scarlet Pimpernel Season 2, Episodes 1-3 will be released in the US?

I watched the 1999 version of The Scarlet Pimpernel on A&E episodes 1-3 starring Richard E. Grant. I just found out today that those three movies are the first season and that there is a second season with three more movies. I was only able to find them on the internet for sale in region 2. Does anyone know when they will be released in the US for region 1?
