2週間と比較するとPS Vita本体の売上が4倍程度になったことをSCEJ河野プレジデントが明かしました。
The SCEJ President, Mr. Kano stated that the Vita's sales were about four times higher than the previous two week period, prior to the price cut.
If it was just the sales two weeks ago, not for the previous two week period, I would expect 2週間前 instead of just 2週間 there. However, I could very well be over thinking it. He says 'compared to the two week period prior to the cut' quite clearly.
I agree. Literally, he says: If you compare to a 2 week period, PS Vita system sales have become 4 times.
In simple terms, probably around 70+k units. Tomorrow's gonna be interesting.
