Years ago the rumor was that they would either have to rebuild large sections of it or Ibox it due to all sorts of issues they have had with it. I believe sections have already been rebuilt/retracked before. It's "only" ten years old, but it was the first to use this track type and with the extreme forces of the ride I think they encountered a lot of maintenance issues behind the scenes that luckily haven't been noticeable to the average guest until now.
I could easily believe that they are looking into an Ibox conversion. It's simply a cost saving maneuver over time. Not sure it will be the next thing on the agenda though, but I haven't ridden OR this year to know how bad it has gotten. Thunderation is already unrideable for many people, and as long as we are talking rumors, I think that might be the next one to go...
