I am buying the medieval market villiage and then either the fire brigade (10197) or the grand emporium (10211) I am not sure which of the latter two will be retired first? I know its not an exact science but some of you have been collecting lot longer than I have and may have a better idea about it. I am not even sure which came out first or anything. I know you kind of frown on the "help me choose sets" threads but since I am not asking for personal opinions I hope this will be ok. Thanks in advance for any help anyone can give on this.
