Rahal and Wilson to test at TMS next week

Does this pretty much confirm Wilson in at NHL next season?

More likely

Other than fans I haven't heard anything about NHL making any driver changes. I know they are sponsor hunting for Graham, but he's young, American, aggressive, well spoken and talented, so really I can't think of a better face for a lot of sponsors out there.
