I've heard that Cornish Pirates are going semi-pro next season, not sure if that's confirmed or just rumour
Ealing are spending astronomically beyond their means - their current owner is happy to pay out of his pocket but he's 87 and I saw somewhere that his family have said they're not interested in taking over the club when he passes, so that's very shaky ground.
Not too dissimilar to the situation that most Prem clubs are in (relying on a sugar daddy) tbf, but Champ clubs even less enticing to investors/sponsors than Prem ones
