Design rules don't change because marketing says so. It is reasonable to begin early processor development in a new process with conservative design rules (in order to be sure that everything works and yields are acceptable) and rework some components, pushing the envelope a little more, if tests allow it; but such improvements are going to be small "without any change in the process". Maybe the same specifications on a slightly smaller die to reduce costs or a slightly higher clock or lower power SKU. Or nothing at all because the tooling costs for marginally improved revised processors aren't justified.
