Don't ask me how I got it, or from who I got it. I also have no idea if this is fake. It was basically "Hey dude. Take a gander at this will ya? Also, ask no questions". I have no idea who this was, and I don't want to have.

This could be as fake as fake can be. I swear I didn't fabricate it (most of these games I have zero idea what they are), and I reverse searched the more "glaring" terms on Google, and found nothing.
Some of these games are *no* news, so this makes me think what the heck they'd be doing at the event. Makes me suspicious. Another point of interest is that for such a BIG thing, making it playable right there without any announcement whatsoever, no trailer, no nothing, it's very weird considering Castlevania HAS a hype going on.
I'm a bad detective. Could someone tell me if this is fake or not?
If this is true. Well, I'm really disappointed with Konami if this is a port from the PSX original, and even more disappointed if this is an original game and is being relegated to handhelds again.
HOWEVER, here goes my Wild Mass Guessing: This could be the final battle between Dracula and Julius Belmont. Only the hype for this title could live up to have "Symphony of the Night 2" as it's name. Even though it's lame.
