nothing will happen at the halving, at this point i'm expecting something major later this year or even early 2017
Beside the block halving and perhaps a very short lasting price increase due to the block size being increased, nothing interesting will happen the rest of this year and next year.
based on the fact that pump occur with a higher probability in the late part of the year(2013 with 1200 ath, 2015 with the return to 500 etc...) i'm fairly certain that something will happen within this year, no expecting crazy thign like 2k or more
but something around a pump to reach 500-1k range is very possible
