You seem to be using an extremely narrow definition of "investigative journalism." Most investigative journalism will go on about as much as it always has. Some member of the team will investigate a topic and write about it. That's what investigative journalism is.

If you specifically mean war reporting, I don't know. I suspect some kind of nonprofit will spring up to fund reports on wars, but that's contingent on it actually being something any appreciable number of people value as much as it costs.
