Jared Richardson says that agile is going mainstream in many areas, but many companies have only made a partial agile transformation which Richardson calls "fragile" or "agile-fall". XP is more focused on what developers should be doing and Scrum is focused on how to manage the product, but they don't really cross lines Richardson says. Seven years ago Richardson published his book, "Ship It," which takes a more holistic approach to agile. Richardson believes that agile is at a crossroads where more companies (and larger ones) will start to adopt agile. The only question is, how closely will they follow the rules.
Jared Richardson is an Agile Delivery Lead at Pillar Technology, which means he goes in and works with companies on agile transformations.
