I think it's time to stop talking about node sizes. This reads as meaningless to me, not because I don't know what nanometers are, but because the nodes are all defined by a set of technological changes that have little to do with the measurements, and they are all very incremental and interchangeable at this point, so each node doesn't require an entirely new fab. Actually this has always been mostly true, but the capital investment of new equipment used to be less than the risk of variance from process modification. I don't think this is the case anymore. I expect to see gradually-evolving processes that are sold to customers as performance targets rather than fixed fabrication methods. Even the designs may need some kind of meta-representation that gets 'compiled' to a process, which may have traveller variances like metallization layers.
Of course we don't need to know everything, but in terms of news, maybe we could reference key technologies in use that have the largest effect on performance targets and downstream process modification.
