If it's predictions(not based on personal hopes), I'd say Konami will only be showing:
- LoS: Playable demo, more info regarding certain aspects of gameplay, and we'll get a slew of interviews, movies and screenshots from various gaming sites like IGN and Gamespot.
- Harmony of Dispair: Will finally be officially announced as being a project handled by some "other" team.
- We won't hear from IGA and will still be kept in the dark regarding "what" he's doing nowadays.
If it's based on my personal hopes:
- LoS: Same as above!! Maybe add on some panel appearances by a few of the voice actors, who give a brief description of how they approached the roles of the characters they play.
- Harmony of Dispair: Officially announced, and gameplay footage is shown that makes it look GOOD!
- IGA makes an appearance and tells us that he's working on a new CV game for the handhelds(but keeps it a secret to whether it's DS, DS3D, or PSP). He also talks about the other "fronts" of the CV series, including the Alucardvania, the CVIII animated movie and Anderson/Wan live action movie.
