I don't know, he's way off on a couple of things. It most certainly wouldn't take 2 months to reprogram shorter trains. I'd assume removing one car would change block times by an almost imperceptible amount. Launches likely are self controlling, and in such short blocks, starting at almost the same speed, I see that being a day of tests.
Next is him saying it would be better to delay now than in a few months. That's just crazy. Many people set vacations around this ride, especially with in opening in the summer. Doing work in November would be infinitely better.
It certainly will take time to fabricate new track sections, if that is needed. I'd assume they wouldn't be changing the pieces, just replacing damaged ones, once speeds and forces were lowered. Switching out a piece of track could perhaps even happen overnight, depending on crane needs.
I admit, I have no idea what has happened, if anything. If the wear on the track is simply paint being worn off, yeah, that's completely normal. If the steel has been warped or dented in any way, that is certainly not normal.
Intamin certainly has a track record of designing rides too intense, and needing major changes immediately (Intimidator 305, Volcano, Maverick)
But I do find it exceptionally unusual that the ride stopped being ran during this period.
