Depends if VT are going to be held to their offer of running it for free or not!
Virgin offered to run it not-for-profit while the judicial process decided on the case.
They have now won their case by default, so the answer is no.
I should think VT might agree to continue under a management contract (similar to the one in force 2000-2008 during WCRM).
DfT might prefer DOR, but there isn't a bottomless pit of spare TOC managers lying around.
Whoever runs WC from December it will be on a care-and-maintenance basis without investment (ie no new trains, services, station upgrades etc).
Not a recipe for progress.
I think we might be in for a string of shorter franchises where the risks are more manageable. Also not good for investment.
