Long term we may see higher clocks, but, at the launch of a new node we often see lower clocks vs the previous node. Further, here is Forrest Norrod talking about clock stagnation and or possible regression.
Now, what he is saying is that there is Less Frequency gains per node, but, you also have to look at history. When Intel jumped nodes, they often had chips that started out at lower frequencies. As the node matures, they are able to clock higher. Also consider that the metals and materials are changing.
Here he talks about "... means that as we continually shrink our processes now we don't get any more frequency, and really with this next node, without doing extraordinary things we get less frequency..."
So, maybe long term we get higher clocks, but, its also very possible that we launch with lower clocks given more cores, higher heat density, and node constraints.
