That seems to be where this is headed. The lawsuit caused the change where you can't advertise the buyer agent commission but it will likely end up as part of the negotiation.
Prior to the lawsuit, I sell a house for $100,000, I expect to pay 5% commission so I would net $95K
After lawsuit, I list the house for $100,00. Accept an offer for $97,500, giving my buyer a discount so they can pay their agent 2.5%, pay my agent 2.5%, and net $95K Same result.
Or, I pay my agent 2.5% and agree in the contract terms to pay the buyer agent 2.5%. Same, same.
