It goes against the policy of "One ICC tourney every year" and they are committed to milk it so for now, it's not going anywhere.
Makes sense. They already planned several ODI World Cups in advance and assigned them to different nations around the world. Am a lot more interested in the T20 World Cups that take place every 2 years instead.
If the ODI format were scrapped, just imagine the drastic uptick in ICC T20 and Test tournaments. Shame that will probably never happen.
