I work in two states, one of which now has a mixed commission model and the other soon going there... we aren't seeing a lot of properties without a buyer's agent commission, but in those cases (mostly FSBOs) I've simply negotiated a reasonable fee to represent the buyer and we've baked it into the cost of their financing. They get representation but don't have to come up with more out-of-pocket.
I would encourage people to ask their agents about commissions and have open conversation. I have a closing tomorrow and another next week and I couldn't even tell you the commission amount other than that yes I'll get paid something. If an agent is paying excessive attention to the commission or trying to strong-arm you into a house, find a different agent. Real estate is seldom about traditional sales - I don't sell you the property, I match-make you to it, IE: I'm here to find you the right property for you, and if I do a good job on your behalf the money will come. Again - if that's not the experience you are having, go find a different agent.
