It seems like most (if not all) of the content is included in a patch for the DX9 version. So mainly you're just getting better graphics and co-op options.

I'm not sure it's entirely known what the differences are until a lot of people purchase it and play through, but this is what's been said by the publisher (below copied from description on page)

Existing Dark Souls II owners will receive a patch to implement these elements: Xbox One, PS4, and DirectX 11 versions of the game will include the following features in addition to those listed above:
 * Additional NPCs added for an enhanced story experience.
 * Parameter adjustments for improved game balance.
 * Expanded item descriptions.
 * Improved online matchmaking functionality.
 * Additional upgrades to graphics, sound, performance.
 * Increase in maximum online players in single session (6 total).
