In case Lego has them pull the info, here's the full list/post:
At last! After a couple of dry news weeks we finally have something interesting to report!
Brickset member supersympa has found entries at a Dutch toy shop website for the next Exclusives:
* 10223 Kingdoms Joust
* 10224 Town Hall
* 10225 R2-D2
* 10226 Sopwith Camel
* 10227 B-Wing
There are no pictures or descriptions yet but a release date of 1st January 2012 is quoted. However I'm sure they won't all be out on the same date.
I think we are safe to assume that 10224 will be the next modular building but what about the Joust set? Something along the lines of a highly-detailed castle themed set along the lines of the Medieval Market Village, I wonder?
I'll let you discucss the others, but don't be surprised if I'm asked to remove this information because I don't suppose LEGO intended it to be released in this way at this time...
