Some day it will be, but that wont be for many years for now. Most gamers prefer physical games. If you continue to short you will continue to lose your cash . With estimated 2014 EPS of $4, this will march up to $50.
I will dip my toe now on short position. You are right. Impact of gaming trends are maybe 1-3 years, but the market is forward looking so pps impact will occur much sooner. Question is does this have a good enough story or mechanics for MM to force a short squeeze? Short interest is high and may be tempting for some. I'll be patient and wait and see for signs and add slowly. I hope to see 50-60 range but I think it unlikely.
