Im gonna put my conspiracy cap on.
I believe that the reason why dsp has started to do trends(late though) and rebranding his dead channels is because his spendings in general have increased or he's strapped for money. I do believe going forward that dsp will get into trends/things that otherwise he wouldnt normally do like: political discussions, model kit building(god no), tierlists, anime reviews, etc. Now as the years progress i predict that he will try to expand(and fail) his business because the reality of "i need to save money for retirement because i cant do this shit forever" kicks in. Mind you he has stated that he believes he will be streaming till he dies. He's getting older and games are getting faster for him, eventually his streams will be just him talking to the camera reminding his dents that he needs money for meds this week, so like his prestreams but cranked to 11.
