10232 Palace Cinema
grogall has uncovered this picture of the next modular building, Palace Cinema. The image has come from shop.LEGO.com, as you can see, but it's not for sale there yet and there's no word on official release date or prices. It must be imminent, though, given the picture's been put on the server.
Note the clear 'Creator Expert' labelling, which it's believed will be used for all LEGO Exclusives (that are not obviously attached to another theme) in future.
The image's release was probably inadvertent, so we may be asked to remove it.
