Is this thread still going?
really? 
A few things:
- PC players have to pay for the DLC just as well. And: the xbox gets them first.
- No CK that does anything useful in this engine could run on the archaic and limited console hardware.
- Sony and Microsoft have pretty much forbidden user made mods on their proprietary platforms.
- The consoles would run into serious frame-rate issues on many (most) mods.
- The CK is not some severely limited and simplistic tool like Halo's forge. Nor can it be without a total engine overhaul.
Also, and this is very important: if Beth would have to distribute the mods themselves (which they would have to on consoles, since there is no 3rd party distribution service available on those platforms) they would have to give customer support for those mods. Giving support requires funds, hence: it could not be a "free" service. And also: giving support for a mod would require Bethesda to "take over" support/development of a particular mod, hence becoming the author of what's previously someone else's work.
Besides the customer support issue, on consoles there's no possibility (exterior programs) to deal with load order issues, compatibility issues, merge issues, etc, etc. On PC Bethesda relies on third party solutions and third party support to solve those. On the consoles Beth would have to solve and support those themselves, which again requires additional development funds. Hence, again, it could not be a "free" service.
In all: No. It won't happen. And you should have bloody well known this yourself. It's always been this way with Bethesda's Elder Scrolls and Fallout games, for good reasons.
If you want mods get Bethesda's games for PC. Same as with any other game franchise out there that gets mods. (<- exceptions to this can be counted on one hand)
