Is this true?
Does it matter? The point being made was that a 32GB option with the existing Skylake architecture will reduce battery life. It is clear from Schiller's email that Apple decided not to offer the 32GB option for that reason. The reason today's rumor exists is because future Intel chipsets will allow 32GB with lower power requirements, making that a more likely possibility in a battery powered device. Would a potential customer of the new MBP be ok with 32GB and, say, 6 hours -- I'm making up this lower number, don't know what it could actually be -- of battery life? Maybe, but Apple isn't.
