I think it will rise even after the Halving. Because people will realise that the amount of BTC is limited. And also, there will be another halving approaching and so on. So i think the price will rise in 2016 and then stay about the same for the 2017.
Price will increase after halving for sure, but we are not sure how long it will be stable, we need price stability in bitcoins that will only encourage more and more people to start using bitcoins, if price is not stable people would never invest their money into bitcoins.
If price become stable than bitcoin will loss it charm but bitcoin need some steady growth rather than dumping and pumping.
