Nope, that's never been a plan for the x3's. They're hoping for better speed bins by cycling through quads and disabling the slowest core or using quads with 1 broken core as a x3. If demand is high for these we might see something along the lines of a true tri-core, but it would likely be composed of a quad core base, with only 3 cores installed. I think AMD is hoping for demand to be just right, that they can continuously produce quads, and sell off the weaker/broken ones as x3's and new-gen x2's. It really makes a lot of sense, and it's absolutely no different than what both Intel and AMD have been doing for years. A new architecture comes out and you make as many as you can. Find the maximum speed, and bin them at different steps. Got an X2 with a busted core? Sell it as a sempron! Got a C2D with a borked core? Sell it as a Celeron! It's only as green as they've been all along. Broken chips get sold one way or another, now AMD can call it an advantage that their architecture is designed as such that there's another level they can sell on. Intel isn't going to pursue it, they'll just adjust prices on C2D's to match performance with AMD. Hate on tri-cores if you want, but it's a standard practice. It's done by both companies, and it's been going on since the dawn of time.
