From the Forgeworld Facebook page this image was captured (and looks to have been removed now) revealing future or near future Last Chance to Buy items for the Mechanicum. It seems these will be going to Last Chance fairly soon. Apparently a new last chance pic was up on the Forgeworld Website briefly before being taken down.
Of course this does mean that there is a list of items that have been reviewed that will be going soon.
The image was captured by Nick Ivers on Facebook.
