I'm not surprised to see another major company licensing a powerful engine like this; hell, I pretty much started to call this a year or two ago. With development costs being what they are it only makes sense. I expect more Japanese companies in particular will start doing this for a number of reasons. Namely because American developers have in general gotten way ahead of most Japanese dvelopers in terms of the technological side of game development, and the typical strategy of building a different engine for every game just isn't as viable anymore.
