They reused that scene where he touches R2D2, so he's there, but not much compared to the others. I'm worried about him too, I feel like they have been way too quiet about his role in this film. :(
I hadn't read that interview, but that doesn't surprise me. He even grew a beard like his mentor! I think it's odd too. At first I thought I was overlooking him (it took me a while to find Leia). I guess he's going to have a minor role in the movie or they might kill him off...
Can we talk about the fact that Adam driver is both Kylo Renn and a member of the resistance? Can you say Jacen Solo anyone? And then Rey is totally looking like a Jaina solo.
