Medieval Market Village (#10193) Previewed March 4, 2009
Coming April 23, 2009. This looks like it will be a beautiful model, combining the best features of the Castle series with the newer Green Grocer and Corner Cafe building sets. While the other Castle sets in the series are focused on warfare (fortifications, siege engines and the like), this model represents a peaceful village, with the townsfolk marketing their produce (although two castle guards are present to protect them in case any of the evil trolls show up).
You can pre-order this set from LEGO.com.
