My speech was about the potential for growth of social gaming. I am pretty sure it was taped and posted on gamerlive.tv
The Wii U comment was in response to a question about the potential for the Wii U.
I believe (and please feel free to disagree) that a large portion of the Wii audience comprised casual gamers--those who bought one or two games a year the first two years, then put the Wii aside--and that those casual gamers moved on to another platform. The "other" platform may have been Facebook games, smart phone games, tablet games, or one of the other consoles, but once they moved on, they are not likely to come back.
At the same time, I believe (again, please feel free to disagree) that the growth of smart phones and tablets has attracted many potential dedicated handheld game customers, and these people also are unlikely to come back to either 3DS or PS Vita.
Summing this up, I think the addressable market for the Wii U is around half of the market for the Wii, and I think Microsoft and Sony will compete for a portion of that market if the Wii U is priced too high. I think that the dedicated handheld market is permanently impacted by smart phones and tablets, and think that Nintendo's addressable market is probably also half of its former market.
Nintendo is in disarray because they waited too long to launch the Wii U. I know that this sounds like (and is) sour grapes because they didn't launch the Wii HD in 2009 or 2010 as I "predicted". They should have, and because they didn't, the decline in Wii and DS hardware and software sales drove them into generating LOSSES. For those of you who aren't financial analysts, losses mean that the company is worth less than it was before. Nintendo stock has dropped by over 80% in the last few years, and the market has appreciated over the same period. I'm paid to advise investors, and none have made a profit owning Nintendo stock. I don't think that many will make a profit over the next few years, because I don't think Nintendo's strategy will return them to profitability.
If the context above infuriates you, go back to school and pay attention, then read it again ;-)
