MIMO is a concept that appears in many different fields, but I guess that that you are interested in wireless communications?
Coordinated multipoint and network MIMO were two buzzword in the development of LTE-Advanced. There are tons of articles on that. Some new topics for 5G systems are the following.
Massive MIMO, here's a recent overview article: http://arxiv.org/abs/1304.6690
The combination of massive MIMO and many small cells is another area of current interest:

MIMO for millimeter wave communications is another topic that is active:

I think combination of massive mimo with space shift keying or spatial modulation could give many advantages
In radar, MIMO radars and signal processing of these systems are in advance. Also, Channel estimation of MIMO systems is another one. In cooperative cellular or non-cellular sytems, MIMO relays are in progress. I suggest you to do the research about power control and beamforming in MIMO wireless communications.
