Great to see the vast scale of this. I often think certain opportunities may have been missed (eg if the terminal has been made smaller when it would cost relatively little to have extra size for future proofing) but only time will tell - certainly I am not best placed to decide this!
For now, the new T2 is likely to be far better than anything there currently, and I hope it causes existing and new airline customers to increase and add MAN services to take advantage of the new and improved facilities.
