With the build techniques being used now by LoR, I would expect that how it is going now we wont see a delay in opening season, but we have an entire winter to navigate yet. The methods that are currently being used, the transport to site of entire walls and complete structures really speed up the process and increase quality, but lifting a 10 meter long wall in high winds is not particularly great, you may as well hoist the main sail. Steel can be lifted in slightly higher winds, but i suspect the weather may have an effect overall. There will absolutely be some slippage written into the programme, it may just be a question of how much.
Right now, I'd be fairly confident, of a 24/25 season opening. Would need a drastic error/event for it not to be.
