AMD's future is HSA, so yes, dedicated CPU's are not part of their mainstream future.
imho, everything will be an APU in the consumer market by the end of 2015, which is not to say:
1. that there will not be products that greatly favour the CPU over the GPU
2. that there will not be CPU sku's created from an APU with a defective/disabled GPU
That's not what basically confirmed rumors say though. The K12 architecture is coming.
Anyways I'm not sure it matters. Intel doesn't create any chips without a IGP (that I know of) why should AMD? Although if AMD chooses too, it should enable them to gain a performance advantage over Intel in theory by dedicating all die to CPU rather than giving up some to GPU (not true now because Bulldozer was so bad).
