Nope. Gwadar will remain a backyard fishing village until the Western corridor is completed. In 1890s Karachi also was a backyard fishing village until the British built the Eastern corridor of it's time - meaning the main rail line running along the Indus which connected Punjab and NWFP with the port. That began the rise of Karachi as entire Indus Basin trade began to flow to Karachi. Once Western corridor is completed entire Afghan, Western Pakistan trade will shift to Gwadar simply because it closer. In fact even westerly portions of Punjab and Islamabad will feed into Gwadar. Down the road even Central Asia could spur Gwadar.
The Western route was not given sufficient importance by Nawaz Sharif whose base was Lahore. Now however Western corridor is in full swing. Interesting the Western corridor begins at Islamabad, goes south west to Mianwali, DI Khan in KPK, Zhob in Balochistan to Quetta and finally Gwadar.
