Guys, I'm going to remove these fighting over windows vs linux posts. Let's keep this on topic please and stop with both the windows vs. linux and the personal nature of these posts.
On topic, I think the article is probably on target. AMD never tells me much other than that they don't comment on unreleased products (until they do, and that's after they have us under NDA), but based on the horribly overpriced FX-9xxx CPUs, I think they may be AM3+'s last hurrah. AMD still has a place and it's a shame many people think they're just out of it at this point. For the price, their offerings are still quite solid, even if their chipset is a bit dated.
They need to get power consumption down and IPC up. Sadly, those are two very challenging prospects. Without software to take advantage of it HSA/hUMA is just a marketing gimmick. For our part of the market, if they could make an APU that has a CPU portion to compete with, say, a 4670K and get game companies to program items to take advantage of that powerful onboard compute GPU (think PhysX for AMD or something like that) that works in tangent with a discrete GPU, that would be a winning combination.
