all i can hope for is the chosen countries have the money when it comes time to actually host it. 7 years out is a long time to bank on and the economics/politics of the host partner can change fairly fast, whether it is within or out of their control... for example, i'm not surprised england was not chosen for any of the events. this is not to say they did not bid (i do not know at this point whether they did or did not), but rather, even if badminton england wanted to host any of the events they're constrained by their major source of funding: uk sport.BWF Major Event Hosts 2019-2025 Awarded
that in itself is sad because past major events held in england (wc, olympics, etc.) always have a great atmosphere.
