I doubt the camera will be used for much more than it was in B/W2.
Streetpass will allow us to exchange info on other trainers for a possible Trainer house, like in G/S/C, where'd you battle the other trainer with their team they had on them, or in this case, possibly in their Battle Box.
I'd like to see Play Coins used in place of Shards when tutoring moves.

I'm expecting StreetPass will be more like mystery gift in GSC but automatically. SpotPass will allow them to distribute online events. eShop and possibly DLC (like new trainers, gyms, areas)? The last part is a stretch, but I definitely think StreetPass and SpotPass will work in those ways.
