That would imply there are no immigration facilities at the new terminal; that you still have to clear immigration at the main terminal.
Immigration time varies with your arrival time. I usually arrive from the Philippines around 5pm; no sweat. But last year my flight on PAL, needless to say, was delayed 5 hours, meaning we arrived along with many flights from Europe. It took one and a half hours just to clear immigration. Incidentally, as a 77 year old, standing around for that length of time is no joke.
