These are not updates.
What is going on with this company?
I think the issue here is people's use of the term "update." This is more of a quiet refresh, which Apple usually does in spring time for various products. Refreshes that don't warrant a big reveal or keynote.
It's clear, especially from the iPad refresh, that Apple is saving all the goodies (better CPU, better screen, etc) for the Pro lines, and establishing these products today as the 'lesser' lines.
