You may want to see Vanguard's methodology and numbers from last year here. Some conditions are definitely different now than about a year ago, though. It has a range of estimates on stocks, bonds, inflation, etc.: Vangaurd 2015 Market Projections
AQR publishes some numbers and estimates stock returns based on averaging an earnings yield approach and dividend discount model approach, with the methodology explained a little more in the 1q14 publication. This also has some numbers for bonds: AQR
For reference, here is the main overview page for the Research Affiliates projections: 
BNY Mellon has their own 10-year capital market return assumptions for different asset classes: 
StarCapital has some handy per-country valuation information and stock market return expectations: 
For some theoretical frameworks and equity risk premium estimates (also some ways to adapt that to other countries, stock subclasses), check Aswath Damodaran's site here, especially the links at the bottom: 
William Bernstein has a simple methodology for both stocks and bonds that is more pessimistic than the above that you can see described in If You Can (from last year; it's easy to plug in today's numbers, though) in the "hurdle number two" section: 
Rick Ferri had a 30-year forecast he publishes every year. Now it seems PortfolioSolutions has taken it over. They still keep with the tradition of quoting what look to me like virtually impossible bond returns on average given starting yields. (now, it's very possible with the right sequence of yield curve changes, but on average you can't expect rates to spike up and then fall back down exactly) 
GMO has a 7-year forecast, which gets reported on by others. See here: 
Here is one John C. Bogle paper from 2015 on the subject, "Occam’s Razor Redux: Establishing Reasonable Expectations for Financial Market Returns": 
The wiki page here cites the Rick Ferri results as well as more numbers from Jack Bogle, Burton Malkiel, and Bill Bernstein:
