Hi,
oh well here we go:
1- Will Skyrim have better animations/blood/combat effects in general?
2- Will we finally see jaw dropping spell effects this time (flame wave, rain of fire, magic missile..etc)?
3- Will combat/stealth/magic system be vastly improved?
4- Will we see many unique looking enchanted items as well as randomly generated loot?
5- Will we see spell books this time around?
6- Will the scale of the game be bigger than OB (bigger cities, more enemies, more people...etc)?
7- Will we be able to Knockout/back stab/climb/hide in the shadows like the thief games?
8- Will we see spears?
9- Will we fight dragons?
10- Will we see better leveling? or no leveling at all just gaining skills/magic/abilities?
well that's about it
