Does anyone have news about what is happening with MICCAI-19 reviews?

The organizers sent an email about the delay of rebuttal period (and reviews) 12 days ago. Currently even the rebuttal timeline in the website (https://www.miccai2019.org/information/information-conference_timeline/) is updated to TBD (It was previously 27-30 May, then updated to 3-7 June, and now TBD).
