Please read the bitcointalk threads below for a (more detailed) answer to your question.  The short answer is that anonymity as an eventual optional feature (e.g. something you could select for some transactions and choose not to use for others) appears to be favored by developers rather than the idea of mandatory application (which would apply anonymity to every transaction).  It is still a matter of much debate how anonymity could potentially be developed within the context of bitcoin.  Again, anonymity currently does not exist as part of bitcoin.
