As you might have expected, custom designs of RX 5700 series are not yet ready. We should see prototypes or early designs at launch. Those non-reference design expected to hit the shelves in a couple of weeks.
Before that happens AMD AIBs have prepared a brand new packing and stickers for their reference Navi-based models. For some reason most of the boxes are black, only Sapphire went a step further by introducing a white packaging (but are customers prepared for such a revolution?).
Jokes aside, AIB cards will launch on July 7th and you should be able to buy them wherever you live.
