Well put...Your estimate does not even take to account the future upside sales potential including that of Sony's smartphones and tablets..And how about what they have to say in their "come see the future" presentation of Feb 20th...Sony already doing well in many areas including movies, etc but those most likely will also see upside moves...
If things go as planned, which today's forecast seem to claim exactly that, then I truly believe Sony to end the year somewhere around 75 to 100 per share. Remember even today Sony has about 2/3 of Apple's revenues but a cap that is a fraction of aapl. Also recall CEO's claim a couple of weeks ago that he expects Sony to become one of the top 3 smartphone sellers in the world.
Any wonder why Sony was upgraded by no less than 3 analysts just about a week BEFORE today's earnings?
