How are people so sure that Manon is coming back for Coachella?

Tbh I have my doubts, but I’m trying to stay optimistic. The word 'hiatus' just throws me off because it usually lasts longer or ends with a member leaving. I’m so confused and I don’t know whether to believe she’s coming back for Coachella, she coming back later than Coachella or if she’s gone for good.
