Cyrus,
the Urban Land Institute and Price Waterhouse coopers has compiled an extensive study on real estate markets for the past 30 years. each year they release a very detailed report that is the answers from a survey of thousands of developers, investors, lenders, and institutional real estate firms about markets across the country and beyond.
In it you'll find a ranking of the country's top markets for each commercial property type, as well as a survey of what the big developers are doing in those areas, like buying, selling, holding, etc.
Look it up on uli's website. uli.org. You're looking for the emerging trends in real estate. it's released yearly.
Korpacz also releases a yearly report with this info, but it is pretty expensive.
good luck.
