That's a wonderful video and I love how happy and exited Steven Hoult gets when he talks to James. 
I think James was just being polite when he said he hoped they could make a trip to NYC during the holidays. I do remember him once saying that after filming Rory O'Shea, that  he and Anne-Marie spent time here during Christmas.   It is a beautiful time of year to visit and if he thinks it's the perfect place, well then  maybe.
