This is maybe slightly off-topic, but...
Many folks here didn't like the format of stroke play for Olympic Golf in 2016. If you were a TV executive from a network that owns Olympic TV rights, say NBC, then what happened at yesterday's Walker Cup isn't going to make you enamoured of a match play team event.
Less than five minutes after the Golf Channel came on the air the US clinched the cup. You can argue that they should have shown more than the last two hours of the event but you would still have two hours of dead air. That may be less of a risk at the Olympics with other sports to show, but it sure isn't going to help those that want a match play format of some sort.
The other thing working against a match play event with large teams (more than two per country) is that you really shrink the number of countries able to win a medal down to a handful, probably the US, UK, Aus and SA. And I don't think the IOC likes that, they would probably prefer that many countries have a shot at winning a medal especially smaller countries that may produce the odd good golfer who could catch fire for the week, like Fiji or Thailand.
