we've had lots and lots of ads for the Panasonic GF3 with X kit lens the last few weeks, along with the second round of Sony NEX ads, and the yearlong (and I must say very cohesive) nikon campaign for both point and shoots and DSLR's. Don't remember having seen any nikon 1 system ads though...
The Nikon J1 advert has just run here while I was reading your post. With Lego toys, various ladies perfumes and a Justin Bieber advert following straight after.
