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

Some random guesses:
- A new regulated USD/BTC exchange hosted by Coinbase? Currently they aren't really an exchange but a broker.
- Partnership with a mutual fund company like Fidelity or Vanguard allowing people to invest in BTC with their 401k.


EDIT:

Speculation from Chairforce1:
BTC ETF launch with Nasdaq or NYSE. The Winklevoss twinz are giving a speech tomorrow.
