After Regin, Campoli and Foligno are signed, there are just too many forwards and not enough cap space to fit even 13 of them in let alone what to do with the extra bodies.
On the right side, the depth chart is Alfy, Kovalev, Neil, Shannon, Butler, Wick and Petersson. There's also Hoffman and Smith to work into an already full roster. Yes, some of these guys can be shipped to Binghamton, but Clouston likes to have youngbloods around, and I think Smith and Hoffman or Butler or Wick will make it, necessitating a move.
So it looks like once camp opens, Bryan will follow through on what he said around the draft which was that there will be some movement with the extra forwards. It's really interesting to speculate.
