Hope we get to see how changing attachments works, soon! I respect Crytek has a marketing plan that seems to include keeping customization a secret for now - but they've advertised stuff like the holograph projector and in the singleplayer footage you can see laser sights so it's kind of weird not to know how the feature works in practice. Rabble, rabble, rabble, opinions!

Changing fire modes on weapons would also be a cool feature to have for Crysis 2's multi-player. I don't think I have seen it in any of the Multiplayer videos, correct me if i'm wrong though.

Yeah, I think it would be really good to include those. However, I think with the new MP style we might not see those, but hopefully in Single Player perhaps?
