I also share your concern with pre-announcements. Remember the last "big" Burst announcement? It was just an Android wallet lol.
Having a well functioning Android wallet is pretty neat though.

Must have been quite some work.
Yeah its nice to have a functioning Android wallet lol. But its not something big like how the PoCC tried to hype it to be. Was that the time when the market started reacting positively then the trend quickly reversed when the big new was really just the Android wallet?
They should learn from the mistake and try not to disappoint next time.
