At the moment the price is already higher than 1300 dollars. I'm sure that the main reason for this growth was good news from Japan. There it legalized bitcotin, which means its popularity will grow
it is over 1300$ at Bitstamp,at Bitfines,for example,it is way over 1425$

Btc-e is closing on 1300$ mark as we speak

we can't pinpoint the exact reason for this crazy growth,but Japan could be one of the major factors,yes
