I personally feel that there are many opportunities still to be explored. Most city sets are vehicles which kinda of gets repetitive, yes it is all right to a certain extent. It just gets to flooded sometimes. City really does lack in the buildings development of a city, yes I realise we have the great and wonderful modular sets, but there are still some people who don't wish to empty their pockets for such a sum. Post offices, schools, shopping centers are all parts of our daily life, yet we see TLG are reluctant to explore such areas. We see sets like the minifigure collection set that are the building blocks of cities only seem to have a life away from it.
I love the idea of the camping you guys have brought up it really brings images of possible MOCs to my head, though will probably never be built because lack of bricks A brown bear sounds awesome, another reason for TLG to bring back the model for the polar bear.
Anyway on a full note I can't wait to see what occurs... Hopefully its not a disappointment.
