They have actually had a partnership/integration for ~2 years. Basically it comes down to using AEM as the "Glass" in front of Magento. Basically just using Magento as an API and doing all of the front-end with AEM. I know there are a couple of big sites that have gone this direction, but I think the M2 API is still not feature rich enough to make it work easily.
