Someone can correct me if I’m wrong but I’d assume Relic still holds the Warhammer rights for a set time in a contract with Games Workshop. This would be true regardless of who Relic are owned by.
Once this is through GW can either set up a new one or not, or cancel the contract with some kind of forfeit to Relic or if Relic are deemed to be ‘wasting their time and money’.
That’s what I assume anyway.
With Relic in tow SEGA could really punch a major hole into the strategy market. Company of Heroes, Homeworld and the rights to Warhammer, along with CAs Total series seems to me like a fool proof combination.
Now I’ve said that expect every single one of those series to get buried under a mountain of rushed, poorly tested games! YAY!
