I really don't know. Since they're being billed as "Keith Urban and others" I expect them to be heavily Keith, you know, since they don't even officially name even one other artist on the bill. I also expect they're going to make him a member of the Opry. You have to do a certain number of performances for the Opry per year when you're a member and he's doing 4 in a matter of weeks. I also imagine he'll play with some of the other artists who do appear since the Opry often has collaborations.
