No, they won't. I wish they would do something like an officially sanctioned mod compilation, but they've stated that they have no plans or intent to do so.

We like seeing the mods that are made by the community, but we have no plans to make them available as official releases.
Similar to Morrowind, Oblivion, and Fallout 3, the tools for Skyrim are PC only. There's no plans to release a version of the Creation Kit on consoles. If you're into modding, we suggest you go for the PC version.
