Lego 60th Anniversary sets 2018
I just saw the leaked page in the 2018 retailer catalogue. There are no images but there are box outlines and the sets range from quite large down to quite small (including a large red rectangular bucket), so sadly it doesn't look like they're going to be UCS style sets.
As well as the bucket there should be one set each from the Town, Space, Castle and Pirates themes, but as to which is getting a small set and which a larger one, there's no new info yet.
Very late this year, but better than never, here comes some - bad - news:
The “building bigger thinking“ sets are all only packs of bricks and no real sets (like many of us hoped). They seem to include a lot of special (but not neccessarily new) elements and will therefore be interesting for MOCers nevertheless.
So it seems as if TLG planed to release real anniversary sets only as Exclusives. That's really a pity.
