First off, please don't think Automattic is the sole development authority behind the WordPress software because they are not. Automattic employs a few people that happen to contribute to the WordPress project. They also contribute some resources as well. But as a company, they are not directly in charge of the development of WordPress.
As for your original question, I think the goal is to continue to improve WordPress as a platform that can be molded to be used in any way people can imagine whether that be with integrated APIs or through plugins. The day when all that stuff you mention becomes core material is the day when a large group of vocal people will scream from the rooftops how bloated WordPress is.
Considering CMS stuff, WordPress 3.0 features a new menu system but more importantly, custom post types which many have touted to be a huge feature. One of the last major overhauls that need to occur for WordPress is the user role/capability system. Once that is complete, WordPress will be in good shape.
