Stobarts were folded into the Westbury Property Group last year; whose main function is to develop Business and Warehousing facilities.
It would not surprise me if in the end the airport is converted into a nice big business park.
The WCML should be sorted by the December tt change and with HS2,3 and 4 on the table journey times by train to London could be cut by up to 1/3rd.
Best of luck....
