Wakanda makes a brief appearance in the Empyre: X-Men tie in. The X-Men are in Genosha dealing with a zombie army accidentally created by Scarlet Witch. Turns out the Cotati are also trying to use the island for a launching point for an invasion of Wakanda. We just see a map of Africa with the kingdom located in the wrong place but it's something lol.
Interestingly, the Cotati seem to know about vibranium and have their own name for it. Even in the FF tie-in to Empyre, the Elder of the Universe knew about vibranium and wanted to take it from Thing. I like that it's a seems to be known to the wider universe. Let's hope a BP writer gets to tell the story of vibranium's origin and how it got to Wakanda
