I think people are missing an important point when talking about Falcon Heavy. Yes it was delayed, but the Falcon Heavy that was eventually launched, was WAY, WAY better then the one announced in 2011. The payload of the 2011 version was almost reached by the Falcon 9 itself. That was one of the major reasons for the delay, not design and production issues. The Falcon Heavy profited from all the advancments on Falcon 9 and it made no sense to actually build a Falcon Heavy before Block 4. In fact the first costumers for Falcon Heavy flew on Falcon 9 instead.
