We're definitely seeing the price drops at the consumer level - 5kWh server-rack-style batteries are below $800 for UL listed models, which is nuts.

Used EV batteries are getting really cheap too, you can get as much as 80kWh for around five grand and use an open source BMS to use it for home storage.
