AMD is down playing Crossfire configurations with Vega

"One of the interesting shifts taking place in graphics is the move away from multiple card setups in favor of more powerful single card solutions. This has been going on for some time now, though up until Vega, AMD was still pushing Crossfire, especially when making performance comparisons with Nvidia. With the arrival of Vega, however, expect AMD to cool its jets when it comes to Crossfire configurations."By Paul Lilly
