There is a qualitative difference in the way people are analyzing large amounts of data. Data Warehousing typically means fairly traditional typical SQL queries on vast amounts of data; a window function might be considered sophisticated. Now, technologies that can do much more are becoming more accessible. Graph, time series, path analysis, fraud detection, customer churn analysis, statistical methods, etc. Disclaimer: I work for a "big data" company that is also a data warehousing company.
