It sounds like SAN base is very much in the cards. Very much up in the air as to when exactly, my personal suspicion is that it will be after SLI... they don't want movement and training churn only to have to do it all over again after SLI. History bears that out, they really needed a SEA bus base the way they were using them, but they didn't pull the trigger . Instead bus people got lots of long SEA layovers, which often involved reflows to cover for the reserves they didn't have in base.
