I do wonder about the processor that will go into the Apple Silicon Macs, and that makes a difference in the question of my next Mac. Will the new processor be the next A-series processor, or will it be a somewhat different beast? If, for example, the new processor is the first of a new series of ridiculously high-performance SOCs, that would strengthen the case for waiting longer. But if it's just a 'next step' in the A-series, that would make a case for buying now.
