AMD Radeon R9 Fury series in short supply due to HBM production issues?

Rumors about High Bandwidth Memory (HBM) issues affecting the production of AMD's Radeon R9 Fury lineup have been circulating for some time now.

Some sources argue these claims are bogus as HBM has been shipping for some time now but today eTeknix reports that based on the number of review samples available for tech sites, there may indeed by a problem.

The site says they will not be able to publish a review on launch day as AMD doesn't seem to have enough supply. Word on the street is there are only 10 samples of the Radeon R9 Fury X for the whole of the EU, and absolutely zero samples of the Radeon R9 Fury! Tech publications will get just two days at most to benchmark the card, before they're cycled to the next set of reviewers:

We’ve caught word that the Fury cards won’t be going out for review, but also that the Fury X will only get 10 samples for the whole of the EU, reviewers will keep the cards for no more than two days, then cycle them around to the next set of reviewers. This fits in with earlier rumours we’ve heard that HBM is exceedingly difficult to produce, as well as rumours that retail stock will be in very short supply due to these manufacturing difficulties. Could it be that AMD simply don’t have enough cards to go around? From what we understand, that certainly seems to be the case. Industry sources are already whispering to us that those actually wanting to buy the card will need luck on their side. This issue will no doubt be impacted even further by the expected high demand for the new card.

Given the very small number of samples available for reviewers, the initial availability of the R9 Fury series may be very limited.
