I don't think anyone is actually saying you can't have expectations for the game. I think they have big expectations in reality. I think most of them expect great characters, a rather excellent story, a great world. These were the things that made BG1/2 great, at least for me. It wasn't the specific story or characters, but how well they were made. I expect this same level of world building from Larian, and I think that's fair. However, I don't expect the same exact characters and story basis, that seems rather restricting.
