Measuring the milky way galaxy's rotation curve is bitchingly hard because we're inside it. Curves of other galaxies are much, much easier to measure and for example Andromeda is likely to be correct. Moreover galaxies with exceptionally large satellite galaxies are known to have keplerian decline, so this could have been predicted. The more interesting recent results is that for some galaxies the rotation curve is flat very very far out (those measurements might not be as accurate ofc) which would imply much larger dark matter halos which are inconsistent with e.g. cmb ringing
