My uneducated hope is that Xi Jinping will consolidate too much power, then die, and the previously distributed One Party system will instead have become a One Man system that collapses before someone else can become that One Man. Hopefully the existence of rebel Chinese cultures like Hong Kong and Taiwan can spur this.

My pie in the sky hope is that the PRC collapses utterly and the ROC begins to rule the entire mainland as well. One China indeed...
