well answer = there is not enough competition to force a 6 or 8 core product out of intel. If BD's 8 core is so kickass, Intel would have no choice but to intro a 6 core or 8 core version to compete. But as things go, looks like we will continue to see only quads for even future generations of Intel chips.
This is a bunch of crap, and you other guys throwing around econ 101 insults at people to back up your point-of-view that more cores is the only valid path of innovation are just showing that you don't have a 101 understanding of it yourselves.
The truth is you (people wanting more cores, MOAR!) are not the market demographic driving innovation. You are not the market demographic driving sales. Therefore you are not the market demographic Intel cares about. You are a minor concern and they already have a product (multiple, actually) that serves your demographic.
Laptop sales have surpassed desktop sales. Battery life, graphics performance, and manufacturing efficiency are driving innovation. All software that was easy to thread has already been threaded. Almost all software that is medium or hard to thread has already been threaded. Not all software can be threaded ad infinitum. *Most* software cannot go beyond a few threads. *Most* software runs fine on a quad core; moving to hex or HT-quad sees diminishing returns. For the minority of users that need non-mainstream equipment, they have products available, and (Econ 101 here, pay attention) if they were able to increase sales and make more money doing it, they would lower prices on those parts. As it is, they have figured out what the market can bear, and they are charging appropriately.
To finish up, you are making a couple very foolish assumptions...
- If there was a market to make money on mainstream many-core chips, you can be sure that Intel would be playing in that market with all they've got
- Intel's engineers are certainly not slowing down or slacking or refusing to push the boundaries of their technology and manufacturing process
