The 1662 version is still technically the authorized version of the Book of Common Prayer for the Church of England. Hearkening back to its early history, the Church of England is still linked with the British state in a way in which most Anglican Provinces are not; the revision of the Book of Common Prayer requires not only ecclesial action, but an act of Parliament. The 1662 version has become something of a "historical national document," and an official replacement of it today would be analagous to replacing a historical building with an "improved" modern structure.
