C# could be major
There was a lot of hype and predictions in 2000 that C# was going to be the #1 programming language. All that we could do at Sun was to listen to what Java users wanted and build the best release we could, that was JDK 5.0.

Yet here we are 5 years later with a new wave of languages getting the attention. Python, PHP and Ruby on Rails get more of the limelight and Java is still the choice for enterprise application development. In my book C# failed to make the grade, not just because of Java but the whole open source language landscape. You can read more of my analysis here.
