If all this stuff about not needing a high-end CPU for games is what you really care about (I care about a whole lot more than just games although I play a few casually), then the i3-4330 that's been available since last year and costs $60-70 less than Kaveri parts that are on the market and is vastly more power efficient has all the CPU power you need too. Sure, its IGP is weaker than Kaveri but... all you need is a cheapo (and upgradeable) video card to easily beat Kaveri... in fact an AMD HD-7750 is one such card.
In another year or two, you can get another sub-$100 GPU as an upgrade that's cheaper than AMD's next-generation $150-$200 APU that will still easily beat whatever AMD can produce in the IGP, and you can keep the (more power efficient) CPU since CPU doesn't matter.
That's AMD's problem, to really promote Kaveri you have to basically ignore other AMD products, so AMD is competing against itself.
In mobile Kaveri could be more successful because the IGP is more important in mobile setups and a lot of mobile parts are still dual core (e.g. 2 Kaveri "modules") anyway. In those setups you can't upgrade the GPU. I'm curious to see what the mobile flavors of Kaveri do, but when there are real quad-core Intel CPUs on the desktop out for the same price as Kaveri, it's silly to think that in the long run you'll be better off with a guaranteed low-end CPU when GPU upgrades are easy and even sub-$100 GPUs are beating Kaveri by a comfortable margin.
