think now's the best time to go tour the new terminal - inside out.
i don't think i'll ever get to be inside the new terminal, ever. unless i happen to fork out more money than necessary and fly with SQ (very unlikely), or fly with other airlines (say, AA) that will operate at that terminal in march.
all i can say is, it's HUGE!

however, HK airport is still more impressive to me. we'll see if this terminal can bring the title back.
