I believe the developer or one of the developers of mintcoin is/was one of the guys with PIVX. With PIVX finished with the implementation of the zercoin protocol, i believe its time mintcoin developers comes back and work on the development of mintcoin.
is it true?
yes, I've been hired as a part of the PIVX development team. My time with MINT has not come to an end, however it is still (as it has always been) a voluntary contribution if and when I have free time. That being said, work does continue on MINT, albeit slowly as free time is almost non-existent right now.
