Hello,
The price in MT GOX is raising from 100usd to 270usd in 3hours or less
The ratio at bitcoinbuilder has also changed from 0.38 gotbtc/real btc to 0.61.
I have no idea about news or whatsoever, but what it is clear is that the price has stop in a double support at 100 and is going up dramatically.
This can be a clear sign that there are insiders or rumors about MTGOX reestablishing withdrawals or technical problems solved.
