Agreed. Huawei is pretty much dead, like Sony and HTC. At least until U.S lift the sanctions, which is easier said than done.
There are, of course, rumors that Chinese Govt. is considering banning not only Apple products' sales but also cutting off the local production of iPhones, which will prompt U.S to ease the ban sooner than later.
It sounds all nice and dandy until you consider Foxconn, China's largest manufacturing industry, which solely relies on Apple! Banning Apple will severely cripple Foxconn as well so China is in no position to take a stand! Besides, Apple can always take their business elsewhere. Economically struggling India comes to mind! India will accept Apple with both arms wide open, willing to set-up any deal with the 'trillion dollar' Californian Giant.
TL;DR Huawei's future is hazy, at best!
