If Omar Hakim does take the job that's fantastic, but I don't think the tour he played on was a test. They needed a replacement, immediately, and Schon got a friend of his to adjust his schedule and do it. Hakim is a fantastic musician, I don't think they would hesitate to hire him if he wanted the job and Steve Smith did not want to return. They apparently called Smith first (no surprise, active with Schon on solo projects, etc.), and there was a hint he might do some concerts with them once his own dates are over.
They have been planning a 'family' tour with Santana, and it sounds like they might get out early Journey as an opening act. I could see Hakim or Smith being interested in that, but it wouldn't surprise me if they also just took Michael Shrieve as a fill in.
