Motley Fool examines Sony as a portfolio investment given the PS3's rough publicity ride, launch shortages, and tough beats at the hands of the buzz-worthy Wii and solid Xbox 360 performance to date. The article suggests further difficulty for Sony calling the one-two punch of the DS and Wii "difficult to overcome," in addition to the fact that a Microsoft game -- Gears of War for the 360 -- was the best selling game in November, not a PlayStation title.

Ultimately, however, the article contests that despite Sony's recent problems (and there's a lot of 'em), investors shouldn't count Sony out in the long run because PS3 shortages won't always exists and early Wii praise could falter over time. But objectively speaking, what possible scenario would reverse the PS3's fortunes? Killer exclusives? Early price drop? What's it going to take?
