How much will Ethereum’s Shanghai Update and the subsequent possibility of unstaking affect the price of ETH?

With the Shanghai Update nearing fruition, I am wondering if the subsequent unstaking might produce enough selling pressure to seriously affect ETH’s price in a negative fashion. Do you guys predict that people will withdraw and sell despite the dire market conditions and low ETH price or will people keep staking? Due to the numerous recent collapses of centralized platforms, I can imagine that many people will at least pull their assets from platforms into self-custody, even if they intend to hodl. And is the daily rate of maximum unstaking already set in stone or can developers still adjust it to prevent deleterious effects of (too) fast unstaking? Thanks for your input!
