At my age my memory is foggy and faulty, but it seems I remember a discussion of a full Bandon course coming in 2020. If WGT has any long term plans, developing full courses from venues that are already under contract makes perfect sense.
Wolf Creek came from a ctth setup for a reason. It is much easier to work on some kind of contract extension between parties that know and trust each other rather than starting fresh with strangers. Bringing back Oakmont falls into this area of an existing good relationship being rekindled.
