The question is, where have the evangelical Anglicans been while the Africans have been fighting the good fight?
The (c)atholic party within mainstream Anglicanism—i.e., the Anglo-catholics who remain in the CofE and who share many of the theological concerns of their evangelical brethren—seems resigned to hunker down behind a well defined wall. Many, of course, have already left for the Anglican Ordinariate. If there is a better opportunity for remnant Anglo-catholics to preserve the Anglican patrimony, it is definitely within the Ordinariate.
Meanwhile, evangelical Anglicans cling to a fiction that for them is their salvation. Sadly, they have not learned from their brethren of the Anglican continuing movement abroad—ACNA, ANiC, et al—that sola scriptura will not solve their ecclesiological difficulties. For one, the differing opinions within the continuing movement regarding the ordination of women. The continuing Anglican movement has only pushed back a few decades an inevitable encounter with the very problematic ideology which has led all of protestantism to the precipice. The Bible alone cannot provide the necessary authority which preserves the authority of the Bible. Only a magisterium can preserve the authority of the Bible. Anglicanism has no such authority. Neither has any protestant community.
