I think Nexus is still very solid phone and we don't know if/when verizon will get the next nexus phone.
But if you are looking at other phones, Incredible 4G seems like the first major phone after Gnex on verizon. 4" qHD SAMOLED screen is a little downgrade from nexus, but it's the first phone on VZW with 28nm S4 snapdragon/LTE in one chip. So it should be the fastest phone on VZW for some time. That is if HTC can pull it off without any major bugs/issues. After that, summer will be interesting time for One X and GSIII.
