so if I hear trance with techno influences.. I can say.. will trance be the new techno? wehhh :P

no, hardstyle is hardstyle and hardcore is hardcore. (gabba)
recent hardstyle may be having some influences of hardcore, but hey.. every music genre has influences of other genres

hardcore (gabba) ripped a lot from hip-hop back in 1995, and trance also covers a lot of 70s 80s tracks.

:D
