Randyt, until this thread, the only person I'd encountered that was never wrong despite the facts was myself.
A 6% downturn in this economy is nothing.
Here are some
facts broken down so you can understand them;
Software: 2010 should have been a big year for software sales with major releases of a number of popular franchises like Halo, COD, Mario, God of War, etc... Still, receded 6% and a number of companies finally gave way under the weight of the economy.
Hardware: Wii was the biggest loser with 38% fewer sales than the year prior, even though they made them in different colors

and did some decent bundling. The PS3 down 11% in spite of the addition of the Move hardware. It's not much of a reach to think that sales of the PS3 would have been worse without it, but that would be speculation. The Xbox360, however, propped up the entire industry with 42% growth. They were literally the only one not to have slid backwards. An intelligent person looks at patterns like this and understands that there must be reasons. I'm still waiting for your hypothesis, if it differs from mine.
Accessories: Up from last year, but this would be obvious. Move and Kinect are major accessory items and they aren't cheap. Cheaper than a new "next gen" system by a long shot, but still costly enough to drive the numbers from previous years.
So while 6% downturn in this economy may be "nothing" relative to other industries, it's significant for a couple of reasons. This should have been a banner year for video games, with big growth. There was a perfect storm of new games based on the major franchises, and new hardware for two of the big three, to expand their capabilities. Yet the industry, as a whole, slid backwards, with some sliding much more than others.
And the other reason it's significant, is that it shows, in a big way, IMHO, that industry analysts and general industry cheerleaders were wrong in their assertion that the video gaming industry was somehow immune from economic pressures that have negatively affected virtually every other industry which produces non-essential goods. It's a wake-up call.
