A few weeks ago the Valkyrie Developers got onto the live Alpha Servers and battled it out with the Alpha Testers. The event was streamed by multiple Twitch Streamers allowing for the first time many people to glimpse what it was like to be in a live Valkyrie match. The event managed to attract several hundred viewers.
Tomorrow (24th of Febuary) at 18:00 GMT the developers will be back on the server for round 2.
CCP Redcape, the Valkyrie teams newest member and Community Developer posted to the Valkyrie Forums:

The last couple of weeks have been incredibly important for EVE: Valkyrie. Our players have been vital to us, giving us feedback, testing the game and being incredibly active on social media, be it streaming, podcasts, meeting us at events like EVE_NT and organizing their own.
In January, we decided to test our Alpha players with a 'Battle the Devs' event and we were overwhelmed with the response, so I?m excited to say we are bringing back the event in February, bigger and better than ever. Battle the Devs II will commence on the 24 February 18:00 GMT, and we're delighted to say some of our Alpha pilots will be streaming.
For those of you who are interested in watching the event, keep your eyes peeled to this thread for links to the stream, and if you want to get involved on social media, follow us on Twitter #EVEValkyrie #BattleTheDevs and on Facebook.
If you're interested in being a part of the Alpha there is still time to join the battle. Check out this brand new video for a taste of what you can expect.

Be sure to keep an eye out on Twitch for the streams which you can see by visiting this link here.
Also keep an eye out for our hands on Valkyrie testing that we did at EVE Nottingham last weekend.
