I’m still hoping they go down the oblivion operatives route from its construction period with the staff/actor training, the whole point of this ride is the mystery of what’s underground, so having people shouting at you kind of works against that. Either way it’s very nice to finally see this back and I hope it lasts longer than just this season and next, but with the effort they’ve put into reopening it I’m confident it will.
I personally reckon it’s been the plan to re-open it alongside the nemesis retrack all along.
It’ll remain open for the forseeable now, as you say far too much work has gone into getting it operational to then close it again shortly afterward. The park has certainly shown that they’re not shy of drafting in temporary rides to fill a void if needed so I’m sure they’d have gone down that route rather than investing resource into opening an SBNO attraction if that we’re the aim.
