I hope you're right, the text says there will be airbridges but the graphic shows two B737 sized stands (preumably with bridges not shown) and a B777 parked on the old stand 12 with the building on the wrong side for a jetway.
The graphic needs to be wholly inaccurate for there to be two B777 sized new stands. It looks like possible two B757 sized stands with presumably airbridge access at the end of the SE Pier with the old stand 12 for up to B777s bussed outside of the new baggage hall?
