Its not unusual for the Mac Pro to go longer then two years before updates. Even your beloved classic Mac Pro.
So there you go, you just verified my statement, thanks.
No he didn’t. You say its not unusual for the Mac Pro to go 2+ years between updates? Its happened once. Its now over 200 days past the typical update length and about a month away from the longest time between updates ever. And you can’t hide behind product cycles out Apple’s control. Haswell Xeons have been out for over a year.
