Realistically though I don't think this is really what happened. I mean is the type of consumer that's shopping for a game system in YEAR 5/6 really looking at a system and saying
"You know the 1500 available games are OK I guess, but I really don't like the looks of this May/June/July release schedule coming up and their E3 wasn't great"
Like I know in gaming enthusiast circles people believe real human beings think this way, but really, lol that isn't reality.
By year 5 of any hardware your existing library of several hundred game titles should be the selling point not the immediate month to month release schedule.
And people also go back and forth on this, like Just Dance selling so big in 2011 proves the Wii could sell software, but then doesn't that also show the Wii did in fact have a massive blockbuster ever green seller? You can't have it both ways.
The fact is too Wii sales didn't plummet really at any one particular point. The drop in sales from 2009 to 2010 was about 6 million less. Then the drop the next year was another 5-6 million. And then another 5 million. It was a pretty consistent downward trajectory after 2008 onwards even with games like Wii Sports Resort, NSMB Wii, Mario Galaxy 2.
Right, and that supports my idea. The sales dropped off (slowly or abruptly however one chooses to see it) due to decreased support.
As for interest in a console 5/6 after release, refer to my prior reply to you, we have plenty of good examples. Remember, HW sales is one thing, SW sales is another. Certainly I don't expect hardware to keep selling too strong for an older console (bar a cool revision like the GBC), but SW sales can persist. A great example is the Pokemon series far into the Gamboy's lifecycle.
