Well rest be asaured Sony will not take any hasty step, they always plan and execute things in perfect manner. This is only major broadcaster which is not into launching channels just for increasing revenue, they invest time and thinking in making proper content, presentation, etc. before taking plunge. You can see this in their channels across genres except Sony Max which in my opinion is primarily sticking to safer grounds rather than fulfilling obligation to bollywood viewers
Also no point criticising them for shutting Rox HD or Le Plex HD as such premium channels depend a lot on subcription revenue, when people r not willing to pay even some basic amount or operators sideline Sony and do not pay them right amount then how can we expect quality stuff.
They had renamed Le Plex social media pages to Sony Pix but have deleted them now, worth to note that Rox social media page is still present but inactive, may be SD feed of this channel will soon be launched which will air only new music thus competing with 9XM
