LEGO has added images for The Hobbit sets to their server although as far as I can see they are not actually listed in the shop yet. We therefore have some great alternative images for them now which you can see on the set details pages linked to here.
Toys R Us (UK) seems to have put them on the shelves in most branches before they should. My local (Portsmouth) had four of the six out (no Goblin King or Wargs) this morning. It has been said in the comments to yesterday's article that 79004 Barrel Escape is a TRU exclusive in the UK which is plausible given that neither Smyths nor Amazon are listing it, so we are unlikely to see it at a discount for a while, if at all.
They seem to be available in the USA in many stores as well now, including Wal-Mart, so I'm told. (BTW, Happy Thanksgiving...)
