I think a lot of people are looking forward to the game, but we may not all be looking forward to the same things.
I'm looking forward to a well-crafted tale set against a broad canvas, with both freedom to act and interesting choices. I'm looking forward to a fantastic single-player experience that is not hobbled by compromises to support other modes. I'm looking forward to being offered inventive and novel ways of interacting with and affecting the world and story. I'm looking forward to immersing my imagined self in the Forgotten Realms, and the spirit of the D&D milieu.
I care not for the game to closely parallel BG2 I care not for the game to closely parallel D:OS2 I care not if the game follows 5e or diverges.
This may or may not be the game Larian are making, and may or may not match what anyone else wants. I shall remain cautiously optimistic until proven otherwise.
