WELL THERE IS NOW!
F and I are going to see the film this evening - can't wait. In the meantime I thought I'd put up my own little tribute to The Force Awakens.
As for the droid - he's C1-10P - Chopper, I know nothing about him as he's one of the characters from the animated series (what animated series??) The box blurb says he's an astromech droid aboard the Ghost freighter. I searched the whole of toys R us for an R2D2, or indeed any other droid, but nope, so I leave you with this thought.
This is not the droid I was looking for!
