Although no announcement is made, SZB is expected to close down because;
1. YTL, a PM favourite company has invested (and made) billions in the ERL (Express Rail Link) and planned to float off ERL in KLSE almost immediately. Ghost trains won't look good to investors and PM can't let YTL down.
2. Air Asia will be successful at SZB and draw customers from Mas. PM won't like Mas to loss more money. On the basis to compete on equal ground, AK will be moved to KLIA.
3. Convenient, cheaper and efficient transportation system is never a top priority in present adminstration.
Just my 2 cents worth of opinion.
