It'll take a lot of small moves for sure. Some news about acceptance isn't as bullish as you'd expect it to be on the shorter terms (combinations of these sorts of news are good). I think the issue is acceptance normally means the market might need higher levels of liquidity in order to cope with the pressure of it as well as acceptance not being the same as adoption (when stores started accepting cards, I doubt many people had one they could use or trusted the technology - that could be the same with bitcoin in these areas).
