That slide is from 08/2016 though and believe the last official word was just the vague 'Vega in H1'. So yes can see the argument for the slip but still not as bad as the 'it was Q1' that was going around and that they've delayed and delayed it.
Could also argue that you'd have to be a real enthusiast to buy the FE and that most are waiting for the gaming cards and it doesn't technically say gaming cards H1 2017.
But it's all semantics and it's pretty clear they've had/are having issues somewhere and probably wanted them all out before H2.
But then if it is something like a HBM supply issue, or some other issue that is a 2nd/3rd party and potentially out of their hands what else can they do? If their supplier is telling them it is coming then they kind of have to go with that, stick to the plan and work around it if needed. They can't really call their supplier out in public by saying we're aiming for H1 but our supplier might mess up and slip us to H2 and then once they know they will slip they're not really going to come out and shift the blame elsewhere.
Either way, it seems more a genuine slip of date rather than an out right lie or pulling the wool over anyone's eyes. The biggest thing - imo - they can be blamed for, which others have mentioned is their lack of official info or any attempt to control the message or public perception.
