There is some chatter in the GPU channel, that would be the AMD Radeon side, that there is activity in terms of the pending launch of Radeon RX Vega, and that would be the consumer part(s).
According to HWBattle, RX Vega silicon ships to AMD’s board partners this week. Custom RX Vega cards will then ship in late-July/early August, shortly after the reference cards. AMD is expected to launch or at least announce the consumer part Vega at Siggraph, which runs from 30th July to 3rd August. Their article is unsourced, but we've been picking up on some of these rumors on the industry side as well. Fingers crossed :)
