In my personal view it looks like Microsoft trying hard to kill SQL Server.
Nearly 100% of the added features in recent releases are available in enterprise editions only, and 2014 is no exception. Sometimes features are in barely usable form, just to be a checker on a box or website. Many SQL and modeling features that are important outside large enterprises are restricted and thus not available to the majority of the user base. This combined with the increasingly complex and costly licencing hinders adoption of these new features. Odds are that people with many years of SQL Server experience are unable to practice anything that has been released in the last 5 years. This is not a good position to be in, let alone culture fanatically as Microsoft does.
Where I work we skipped the 2008 R2 and 2012 versions. What they now offer in the 2014 standard edition is simply not valuable enough to upgrade. Are the design problems they introduced in 2005 and 2008 resolved in 2014? I have read nothing about it and can only assume they have not been. They keep introducing sparsely accessible features, which sometimes are just half implementations and/or incompatible with existing features.
Microsoft and even some of its users typically forget that SQL Server is a foundation/enabling product that other software solutions are build upon. This means internal incompatibility issues, silly limitations and exclusion of useful functionality in lower tiered licences are costly to deal with in these depending products. No-one in their right mind is going to make software that relies on any of the features that customer systems might not support. Or invest in development of libraries that leverage such features in one project when the next project might need to run on the lesser tiered version the customer has. This reduces typical use of the database to the 2000 level (bunch of tables, views, some basic indexes and procedures). If you are lucky you find use of some features originating from 2005. Most people i meet trough work are at this 2000 usage level!
In my view Microsoft wasted almost 14 years, and they do not even realize it. That is how bad they manage one of their core products!
