I don't think there will be any radical price movement. Way too many people are expecting it.
Just a useless gut feeling but I think BTC will keep slowly raising and maybe it will reach ~$600 at the end of the year if we're lucky, but nothing crazy in July or August.
Everything is possible, I think a big BTC pump is due this summer, way too many good news, and the halving is an huge psychological factor for hype and expectation which may ignite the actual fundamentals to blow up and give us a new ATH.
As far as alt goes, the good strong alts (MAID, ETH, XMR...) can always pump high at any given time when least expected.
