Marketing doesn't equal economics.
If it did Windows Phone marketshare would be more than within a margin of error of being statistically irrelevant.
Here are some economics.
1. Europe is fucked. The market is going to have less of an impact on the future of consoles over the next decade then it ever has, in the history of gaming. Every country owes every other country money. Well, except Germany and England. However, to pay back Germany in England, all the other European countries need to get the money they lent back from the other country which is in debt as much or more than the first country. Meaning Germany and England will never get their money back. Don Drummond said the only way for Europe to get it self out of this hole, it to cut all wadges in effected countries by 50 percent across the board. This won't happen. Meaning they all must default. If they default, Germany and England then become broke because so much of their inherent wealth is tied up in assets such as loans. Meaning, nobody is going to go out and drop $400 on a console any time soon. As the decade moves forward, this issue will only get worse. Why? because they have not in-acted any of these measures yet to stabilize the European economy. So, peoples pocket books, outside of Greece and Spain have yet to be hit. Believe you me, it's coming, and it will be coming this year. Which is why banks like TD are getting ready for it now.
2. Since Europe is largely fucked, lets take a look at Asia. Well, everyone in Asia hates everyone else. Japan is gearing up for war with China, and China doesn't buy consoles. Japan also has no money, and is going to have to take measures to fix their economy as well. I mean, they barely give a shit about consoles as it stands, when their paychecks begin to go down, and they begin firing people to keep margins at an acceptable level, they will give a fuck even less about consoles.
3. This leaves us with North America. Where, although bad, Americans economy is a hell of a lot more pretty when it comes to a supply/demand curve then anything else in the world. Canada is fine, Canadians are always fine. So, what is the most popular console with core gamers, and parents of core gamers in North America? Thats right, Xbox 360. So on the one continent where sales are going to matter most this coming decade, Xbox already has a larger presence, and already sells more games then anything else.
4. So now, what is in Microsoft's best economic interest. It's to push their console. Now this is where the marketing comes in. Since economically, it makes sense to squeeze what they can out of Europe, and tell marketing to shove Xbox 720 down the throats of North Americans. North Americans can afford it, their buying more goods then every before, each Christmas since 2008 sales have been going up, the unemployment rating is dropping, and the next Xbox will be able to replace many different items in the hosehold. Making the average person more likely to buy one then 3 separate items. Now you takes these factors, of course in significantly more depth. Find what you feel the demand is, talk to your manufacturing partners and estimate what you can supply, plot these points, and find out a price point. All signs point to, not a Wii U failure.
