First RAZA is not an unlicensed theme. It got licensed from zidware (the art) and not only that but also over the years the theme got enough intrinsic value to be on level with movie and band pins. Same to a degree though not that intense MG and AIW.
Second like others said before the time for original themes is over they should concentrate on the 80s movie license and the JPOP themes first at least first before investing (more) in the revealed unlicensed themes.
