That is exactly how markets work in cases where you don't want to end up with multiple competing systems. We've seen this with the Bluray/HD-DVD debacle, with VHS vs. Beta vs. V2000, and in the financial sector with credit cards.
The end goal of all participants is a monopoly, and the quickest way to get there is by forming alliances or buying out the competition. The largest alliance benefits from network effects and soon can offer lower prices than the competition. The majority of consumers vote based on price, not on technical merits, and we end up with the largest alliance/best-networked player as the monopolist.
All I'm saying is that this isn't the best way to decide which system should be used for important, big-impact items such as payment systems. There should be standardization, not a commercial free-for-all.
