Images of the Lego sets for Poe Dameron's X-Wing and the Millenium Falcon have been released and they reveal a few interesting details and new character from TFA.

First off; we now got confirmation that BB-8 is actually Poe's droid as he comes with the X-Wing set.
Poe's X-Wing's got a pretty unusual paint-job as well.

Included with the Millennium Falcon set however is a man called Tasu Leech and a Kanjiklub member. I guess these two would be the ones who stole the Falcon and brought it to Jakku? It's interesting how one of them is just a "member," while the other has a name. It's possible then that he might have some relevance to the plot. Presumably he's some old acquaintance of Han Solo. Another interesting detail is that their weapons look kind of primitive. Of course it's hard to tell exactly with legos, but it looks like a musket and a pistol.
