Several of Trump's co-defendents are already petitioning a federal court to remove the case. It is widely speculated that Trump himself will try. This question resolves YES iff any of them succeed and NO iff no defendent is successful in having the case removed to federal court.
To be very clear, if someone starts cooperating, the case drops, they die, etc this will resolve NO. The only way it will resolve YES is if someone successfully convinces a federal judge to remove the case and for that removal to be upheld on all reviews.
UPDATE: Trump himself has elected NOT to try and remove the case to federal court: https://www.documentcloud.org/documents/23997414-23sc188947-notice
