My thought process on that comment was that the new change will have more cards enter/rotate out of standard per year, thus, more total cards will be printed.

With the shift by WoTC to do away with Core sets and increase the number of “blocks” per year, we will see even more cards reprinted than ever before.

What makes you think this is true? Part of the reason for going to the new block structure is because they were running out of ideas in the old one by the third set. This+cutting a set that is 50% reprints would imply to me at least that the # of reprints printed in normal sets will be going down, not up.
