Yep, looks like it's Daniels, not Sydow in the pic. Has that caption been on the site the whole time? Didn't notice it before.
And I can totally see Lando and/or Wedge showing up in future installments. Having eight cast members return all at once seems a little much though, so, again, it makes sense to me that they're not in this.
Also, I am fully expecting them to surprise all of us and announce that Serkis will not be in a mo-cap role.
