I think you'd be surprised. In any manufacturing organization production is planned several years in advance and I'm sure Shimano is no different. Any workflow disruption takes forever to correct, witness the current worldwide seminconductor capacity crunch. Shimano's fire would have been a huge disruption. First, the factory in Japan is the only production facility in the world that makes DA and XTR, they couldn't just shift capacity somewhere else. That one source was completely devastated by the fire. All of the line equipment in that factory needing replacement isn't readily available, it's almost certainly all custom made, hugely expensive and would have long lead times from suppliers. Secondly, once the factory was back to being operational (which likely took many months if not a year), setting up the line, building out tooling, training staff, transitioning over from the older models... it all takes forever. The new DA should have been made available a while ago, the fire is a major reason why it wasn't.
