I'm not entirely sure what point you're trying to make. Intel markets and segmentizes their product stack so they make maximum profit. If you think for one second that they will make more money selling 8-core parts as part of their consumer line, you're wrong. Intel has a lot of highly-paid, very smart employees who are very good at what they do.
Why do you need such a large RAW buffer? I assume you're not shooting professionally, as you would already be ordering a 1DX or 1DIV (guessing you are currently shooting Canon by your interest in the 7D).
I wasn't agreeing or disagreeing with you, merely pointing out that the meaning of 'utility' will vary from one person to the next. There's no "tone" inferred by my post, I think you're reading into peoples' comments a little too much.
