I want to hear what you think might be tomorrow's announcement.

I've absolutely no idea.

But they don't have a history of hyping hot air, unlike blockchain.info's habit of insinuating wonders that end up being very exciting for them and no one else.

It seems a bit tongue in cheek to be something truly enormous.

Agreed. I'm wondering why would they would present it like this instead of an update on their blog or a tweet? Seems really strange... makes me want to buy a coin or two today, but I'm resisting the urge as most hypes I've seen previously end up being let downs.
