As you all know, AMD is yet to release the enthusiast SKUs for their graphics card line. The Radeon RX 490 series will be based on a GPU called VEGA 10. We already know that AMD Radeon Technologies Group (RTG) chief Raja Koduri tweeted that development of "Vega10" had just crossed a milestone, although it's a long way to go before you can see it".

AMD was supposed to launch their high-end class VEGA (codename) product in early 2017, the latest rumor was that the launch was being moved forward towards October. However today on Facebook Chris Hook, Sr. Director, Global Marketing and Public Relations, Radeon Technologies Group at AMD posted a photo with the comment "This is the Vega launch venue. Shh, don't tell the press". Considering half the worlds tech press is on his facebook, that obviously was a rather subtle joke slash hint.
  

Not exactly what you'd expect for a product launch - but for gaming series graphics card it certainly looks like a scenery from a Batllefield'ish game?

If this isn't a complete pun (and I do not expect it to be) then AMD is preparing a launch event for VEGA. Let's say you start planning such an even two months up-front, then indeed you can expect launch time to be October ...

So After Polaris comes Vega, Vega is the brightest star in the constellation Lyra, the fifth brightest star in the night sky and the second brightest star in the northern celestial hemisphere, after Arcturus. On earlier roadmaps VEGA was tagged as a HBM2 product. 

On the venue ... I better get my Tetanus shots.
