First amazon uk gives a release date of the 22nd, then Barnes and Nobles says the 28th. What's going on? Is it coming out in October or November or what?

Until they're is an official announcement the big stores tend to just guess. I'd just wait for FFG to say something..

FFG's "Upcoming" section gives a pretty good idea about releases. Much more accurate than any other 3rd party.

With so many factors outside of FFG's direct control (shipping delays, customs inspections and product defects), it is really for the best to shoot at a wide target date and announce a smaller more accurate one as the product is in their (or the dristributors) posession.

It can be frustrating looking at Quarter 4 and remembering that can be October, November or December. It is still better than nothing at all, which is the way many other game companies opperate.
