I don’t think there has been a dramatic shift in the past year as to what skills are in demand, so I would expect what is hot in 2015 to be similar to 2014:
Programming and application management.
Business analytics and big data.
Computerworld had an article on a similar topic last year - The Hot IT Skills for 2014. While the order may be shuffled, I bet the list will have most of the same skills on it this year as well.
