Animal Charity Evaluators identifies a list of mainstream animal products in three categories in order to forecast when cultured versions of products in those categories will be cost-competitive with farmed versions:

• Acellular: Milk, Cheese, Yogurt, Cream, Gelatin, Egg Whites
• Ground Meat: Ground Beef, Ground Chicken, Ground Pork
• Whole Pieces of Muscle Tissue: Chicken, Cow, Pig, Fish

I'm especially interested in any big changes to cost and availability that have happened since the last update in late 2017 (in fact, the article has predictions by some people that some cultured acellular products would be on the market now; is this the case?)
