Eventually a lot of products (not just from Meguiars but, all companies) are going to go by the wayside or get reformulated if they don't meet upcoming VOC requirements. Not sure where DACP stands as far as VOC compliance but, if it doesn't meet them it will have to be reformulated. Meguiars just finished revamping the entire Detailer Line and you can expect eventually they will do the same to the other lines.
Here is a link to the California Air Resources Board search page. There is a lot of information there regarding the upcoming regulations. I found a lot by searching for "voc wax".
