I think you mean 'tick' for a die shrink, which is Denverton, and is supposed to have "more cores and more of everything". 'tock' refers to a new microarchitecture, and the details on the generation that will follow Denverton haven't been announced yet.

There's also going to be the Broadwell SoC, which will fit somewhere between Denverton and E3 v4's.
