Nothing uncommon that deliveries take time. A very large part of the effort goes into firmware development and also power and heat management. The initial announcement of the X1D was very early with largely unfinished firmware. Software development very often falls behind schedule, especially the first time you do it.
As you know, Sony makes the sensors and their factories were hit by a major earthquake, production is up and running now, but they have a giant backlog to fill. So, sensors may be a bottleneck.
Well, it is a long wait. I also had a ling wait for my Sony A7rII. It was announced early June and I got mine in September. Hasselblad will ship X1Ds in numbers when they can. Be sure that they do what they can to get things into production.
Speaking for myself, the problem that I have with the way that Hasselblad has handled the X1D rollout so far isn't that they need extra time to finish complex firmware, get sensors from their vendor, debug heat problems, or whatever else they might be doing to get their product ready to ship to consumers. They should take all the time that they need. Building a new hardware/software platform is incredibly hard work.
My problem is that they've taken orders from dealers who in turn have taken pre-orders from customers. They have thrown out several dates and have missed them. They've completely failed to communicate why they continue to miss dates. And. They're doing victory laps about how successful the camera launch is and making posts on social media channels about first units leaving their factory in Gothenburg without any indication whatsoever that a single photographer has received a production version of the camera, and no believable indication when they will.
If they needed more time, they should have announced the camera with some super vague date like "end of 2016" or "spring of 2017" or no date at all. Then they could have had salivating customers anxiously awaiting the opportunity to buy the camera, without said customers being disappointed after putting down their credit card or deposit and expecting a piece of gear to arrive on the date the manufacturer communicated, only to have that date pass with no explanation, multiple times.
I just cancelled my pre-order. I don't believe that Hasselblad knows when they're going to have units to customers, and I don't enjoy repeated disappointment. I also don't want to stop caring about when the camera is going to arrive while I have a $14k pending charge on my credit card that could hit at any time.
So I'm going to do the rational thing, which is wait until the X1D is a real shipping product, not vaporware, given that I don't "need" one in any real sense. I'll wait for dealers to have stock and/or believable delivery times. And I'll wait for other photographers to get their units and report on whether the hype is merited. Then I might buy one. Or, the Fuji GFX might be on the market by then, and prove itself the superior choice, in which case, I'll save myself a few bucks and buy one of those instead.
I wish Hasselblad much luck.
