You can't ask Hamilton about future sets in the friends series...because all of their accessory sets run together. I actually called once and had a knowledgeable person (shocking isn't it) and he informed me that when you look at some of the future sets listed they're clearly for other villages. (Some had names like Pooh and Piglets snowball fight, etc.) He said they really have no way of knowing how many accessory sets will be made...it's all based on public demand. If people keep buying them the artist will keep making them, and once they end up with a lot of sets back stocked they'll put a stop to their orders from the artist. So while it apparently is totally possible for the sets to go into the 60's they have no way of knowing that now.

My order page on CT is actually updated and says the next set is titled "Holiday Mischief" and should ship sometime soon. As for the sets with cars costing more money...you might want to call them about that. Because all of mine have been the same price. Now shipping has gone up by about a $1 in the last few years...but other than that, the only set I have that cost more was the Simpsons Gate...but that isn't part of the festive friends series and had to be ordered separately.

If you ordered ones and they come and are Simpsons please post pictures and let me know the names so I can call them up and order them.
