It has been up and down a lot this season, and I have heard that after its most recent closure it needed a lot of work.
If they were getting rid of it, I'd be surprised they removed it so quickly. It's easier, and likely more cost effective, to just leave it in situ until end of the season, when the manpower is more available and engineers aren't focusing on running the park. So I do expect it's being removed with the view to do work to repair it.
Equally, one has to wonder at one point they cut their losses with Samurai. And if they do, what they do in turn? Surely at some point it's more sensible to buy a new top scan? And even if they decide not to, the park ideally can't lose a flat ride, especially in that section of the park.
