My guess is that the patch for the full release will not be small. Not as large as the full download for the expansion obviously, but still fairly large so that all the new content will be compatible with entering old areas, and thus compatible for players without the content to see and interact with, (Read: materials, armor, weapons, mounts, and minions)......
