It's not outdated. Many ideas there, like mixture models or hierarchical models are pretty timeless mathematical concepts. A nice follow up is [1], which delves more into more technical inference aspects. There are also follow up texts by the same authors [2,3]. Another approach to further learning is to implement your own library. My favorite implementation is [4], which is both advanced and easy to understand.
