I understand this makes you quite happy, but you really should have waited for the rest of the day (and given this whole thing a bit of thought) before airing your schadenfreude. Karma is a ...you know how it goes.
The points from Indonesia '18 have already been subtracted. Momota went from 111k to 108k, SYQ from 90k to 89k and Axelsen from 79k to 75k. Chen Long is out and will remain at 75k after this. The only one left at the top to put "pressure" on Momota's WR points is CTC. Even if he wins the tournament, he will not surpass SYQ's tally. Given his lacklustre year so far and the fact that he has never won anything above a Super Series/500 even his entire career, I would not exactly call him the heir apparent, future winner of all big titles, anytime soon.
The rest of the field JC/AG/KS/SWH is over 40k behind Momota.
Axelsen and SYQ are currently injured and who knows when they will be back. They have to defend points, too. It might be that after the WC, Momota is even further ahead of them, though I won't be engaging in any pointless (hah!) speculations about that
Fun fact: even if Momota does not win a single match in Japan and the WC, he will drop barely below 100k.
All in all, I wouldn't hold my breath on KM losing his #1 status anytime soon, if I were you.
