I'm waiting for Zen, but I'll hold my breath on the APU. Even if they integrate HBM that's going to be a rather large die with low yields to try to cram a GPU comparable to a modern mid-high to high-end GPU (that already has a die size bigger than most modern CPU's). Still, even a moderately powerful APU would work nicely in tandem with a future RX 490 or whatever AMD puts out for their Vega cards.
