Before anybody corrects the title, I am basing this off the leaked information that the Core m3, m5, and m7 will be rebranded the Core m3, i5, and i7 with the next generation (Kaby Lake) chips. The m5 has seemed like the sweet spot and a significant upgrade over the m3, which, along with the speed boost from the new chips, could mean power isn't an issue for almost all buyers (assuming others will get the Pro). If this rebrand occurs, do you think Apple will keep the m3 model around or replace it with the Y-Series i5? It seems to be the logical option since all other Macs have i5 or i7 processors, so I don't think they'd continue an 'm3' among them. It also make sense if they will use the M processors for larger models of the MacBook (in terms of power and branding). UPDATE: The i5 and i7 naming for the 5W processors has been confirmed in the official Kaby Lake announcement today. That, along with the similar price of m3 and i5 cpus and the exclusion of some features from the m3 back up my argument.
