If we have no external problems and BTC can just hush along as it pleases i expect this rally to be lasting a while. Nevertheless if the blocksize fight escalates again in July it might be the end of this bullish cycle.
I hope that Luke, Adam and Matt will fulfill their promise and deliver the HF code, otherwise we could see some ugly High Noon between chinese miners and Core and you can bet that markets won't like that.

You are deluded if you believe that BTC upwards price movements are dependent upon meaningful progress being made towards an actual hard limit increase or a hardfork proposal.
More or less a large number of folks have come to realize that bitcoin is not broken, and the made up issue regarding lack of scaleability was a kind of ploy to either keep prices down or to debilitate bitcoin through an attempted change of governance. Anyhow, price are going to largely move independent of those kind of attempts at FUCD spreading... whether price moves up or down will be more a product of how much resistance is achieved in the $750 to $850 price arena, rather than some of the inflated scaling hardfork nonsense.. that seg wit should sufficiently address and other subsequent considerations will also adequately address any semblance of actual scaling issues.
