Im interested in the vega 56 line up, which is basically a 1070 card but with HBM2 ram for coins like Zcash could be really good.  Im really hoping this will turn out to be the mining sweet spot for rig density and price/performance but that all depends how it performs, ETH not good for HBM2 but some of the others could end up being nice.
