I find it unlikely that it would be closed in the long term. Private investors or manufacturers will buy the assets and would most likely keep the track open - seems like there is more than enough demand from tourist days, races and mfg testing to support maintenance of the track and facilities.
Still a sad story and a complete mess that will take time to sort out. Too bad this is coming at a time when ED for M cars is effectively filled up for the rest of the year.
