Idly checking the EZY app this afternoon, I see that the flights previously being sold from next weekend have been cancelled. Flights start being available in the app from 01JUL (which is a Wednesday, so that seems like an arbitrary date rather than a considered start date).
BRU - I can't see much enthusiasm for running BRS-BRU as a standalone point-to-point route. When I've used it, the majority of people were connecting on via SN's (reasonably-priced) European route network. Maybe someone will come run it as a codeshare with SN, much as BM did until that fell over? It seems like a very long time until things are sufficiently stable and recovered enough for that to happen.
