Seems its hard to keep all the info on these cards in any sort of real order. To the best of my knowledge, based on both official info and rumors:
The GPU known as Fiji (HBM all that jazz) is internally known as the Fury X. Whether it will keep that name in retail is still unknown to us plebes.
There are potentially a few boards which will *possibly* be the Radeon 390 X/XT/PRO/Ultra-mega/ePeen edition, whatever. These are Hawaii architecture respun on Global Foundries' Mo' bettah 28nm process (original Hawaii were TSMC) and paired with 8 or 4GB of GDDR5. The pinouts and power reqs should be the same, or less in the case of the power draw, so the same PCBs would work just fine for reference boards.
As for that PowerColor board, reading the article they state that it could change some (aesthetics) as it won't be available for a couple of months still.
