I've seen it being advertised that GW is sponsoring some in store events during the weekend that 8th edition is being released in July.
So far seen ... a mega-battle starting on 7/9 in the evening and going to midnight with the first three turns being played with 7th edition, followed by the last three turns using 8th, starting at midnight. Then on 7/10, there will be Buy and Build as much as you can for 4 hours and whomever does the most and the best looking wins up to $50 of plastic sets. And following this there will be a 500point tournament with the same prize as the Buy and Build.
Anyone else seen this or other things, too?
