Umm... I hope I'm not too late to get in on this. But here go a few...
-Are you planning on refining the controls do to the fact gamers found the ones in the previous installment a bit slippery? Could the sense of action be touched up?
-Are there going to be as many small tasks to complete, which some gamers felt tedious and got in the way of the story?
-Is the same graphics engine going to be used or has a new one been designed to deal with issues in the previous game?
-Is it possible to play as some of the evil characters so as to get a feel for the different stories as they come together? Sarumon as a playable character would certainly be interesting.
-Perhaps some strategy could be incorporated? It would be neat to try and plan the Ents' attack on Isengard and then have to carry it out yourself. Treebeard would make a great playable character. Could strategy also be implemented in protecting Helm's Deep?
-And finally, do you feel the voice acting in the game can be up to par with the movie? What can you add that's unique to that and part of your vision?
-Are the cutscenes going to be more cinematic so as to put the movie liscensed game in its place so as to promote your own vision?
Just some ideas. Hope some of them are good questions

Thanks Harry for the great interviews and stories you've been doing!
