I'm sure it was talked about at one point somewhere on Facebook by one of Slatyford's managers that 19204/5/11 were due to cascade out of the region eventually, with Stockton then down to gain 19385/6/7 to replace them. Obviously that now won't happen but I would guess 19383/4 (once 19384 has gained its new engine) will return to the Busways side (Sunderland will definitely need one for the SL6 in Durham - if Stagecoach haven't given that up with the lose of the Prior contracts and the large win in terms of Nexus contracts) and the other 3 depart the region.

Indeed, 19204 is already off the fleet at Stockton - it's been parked nose into the back fence with the remaining Covid-19 reserves since last Monday.
