Right now it'll take 3 blocks before a transaction with standard fee gets 1 confirmation, so transactions will get to 6 confirmations much slower than normal. Add to the fact that falling prices causes miners to shut down, but difficulty will stay high for almost another 2 weeks. This could cause transactions to get even slower. Slower transactions will likely be interpreted as a sell signal by traders, causing the price to fall more and more miners to shutdown and so on, exacerbating the death spiral further.
People have suggested that mining is so centralized at this point that they will likely coordinate to ensure difficulty can fall gradually along with the price. I really hope this will be the case. A hard landing would be really, really ugly for all of crypto.
