There are some changes happening, but certainly MySQL will dominate pre-existing installs for the foreseeable future. Switching databases is not trivial for most applications. Here's a blog post from 451Group in May 2012 about a survey they did: http://blogs.the451group.com/information_management/2012/05/25/survey-results/ http://blogs.the451group.com/information_management/2012/05/... And a specific bit of the presentation linked from there that I found interesting: http://www.slideshare.net/mattaslett/mysql-vs-nosql-and-newsql-survey-results-13073043 http://www.slideshare.net/mattaslett/mysql-vs-nosql-and-news... Slide 20. It's certainly not conclusive, but it is interesting.
