I was in the neighbourhood yesterday and went to have a look.
No activity in the old terminal - it's empty and sealed off - so I went to the office building next door and spoke to a gentleman there. He confirmed that the office building will be the new terminal (as airviewer said above). There was no sign of any work to convert it into a terminal, so unless there's some intensive work done over the next seven days, it will only offer some pretty basic facilities.
I took some pictures. Here's the old terminal in the centre with the office building on its right.
Close up of the office building (ie the new terminal).
I had a peek through the window of the old terminal - you can still see the check in desks inside.
