Simple I don't have to ask them all, 30 million Wii's tell me that 30 million people bought Wii's, regardless of what they think of the console that's 30 million people with Wii's.
Now who's throwing statements out of context? I'm speaking about the ones who buy software not the ones who don't which by the way in a string of articles today, (which was common knowledge to anyone on this site) NPD disclosed that the Wii sells nearly double (it's getting there even faster with every console sold.) the software of PS3 and a little less than double to the Xbox360. That means you'd have to add up the HD install base total software sold from 07-08 fiscal years to say what I said above, which is that for now, your correct in saying, more gamers preffer HD console values over Wii's values.
Probably before you were born people have been considering "what is game play." the software can be played sure, but (let's pull a Bill Clinton) what is play? The game is nothing more than electronic information on some medium, in the past consoles used to in your hands, then the controler become part of the player while the console was it's own entity. In fact the name controller means it is what controls or is used to control, Wii-mote is changing that to (slowly) motion control, in other words your body does the controling, combine that with the balance board and now 1:1 and maybe depending on it's usage the wii speak and you have yourself control using your body.
Sony hit this on the head with Eye toy, but the software or the game did not incorperate it well and the play sucked, thus the games sucked.
(The games had very bad tracking. This by the way is the same arguement used for Wiimote, but Wiimote isn't a peripheral and Eye Toy is.)
I paraphrased Nintendo when I used the word Core, they use the word core from a sales perspective, and I am speaking from a sales perspective, not from internet forum slang perspective. Nintendo apologized for what they did wrong at E3? Time will tell if they did something wrong, and I read that statement by Iwata and it was what it was, he stated that they had no intention of showing games that weren't ready to be shown, and that he's sorry for that. The narrative of the author is what claimed hardcore as being the ones he's apologizing to - the author wanted to feel like Iwata was apologizing to him, that's all.
So in short if your saying I'm using the word core incorrectly, then your saying Nintendo used the word wrong, I'd reccomend you call them up, just be polite and I'm sure they will refference you to wikipedia or something.
Anyway back to the second paragraph; the only legitimate and the only way that matters that consumers express that they like something is if they purchase that something, ("show me the money.") That's the point of business, 30 million Wii's sold, more software sales on Wii versus either the PS3 or 360, but of course you could argue: "Wii's install base is almost 50% it should be equal to both Ps3 and 360 for the fiscal year 08-09." I'd say that the Wii wasn't anywhere near 50% for the duration of that year, it's got a very short shelf life and thats all.
Remember consumers express their values by purchasing product. So, since the Wii sells faster and the software sells more (the Wii's core or in terms of sales the ones who appreciate the value of that product or in gaming that platform) it's very safe to say; not everyone needs the values of the HDTwins.
