Today, producer Erwan Le Breton wrote in the comments to the Necropolis that a new artwork will be released soon, and it will be the last creature of the Necropolis (he says they haven't shown you the last unit of the Necropolis yet). We're waiting for the spider queen... He also wrote a comment about Haven (they will show 2 units soon). In general, he says that tomorrow we will see a new artwork. I hope he's not lying. In that case, since he didn't write anything in the comments to Inferno, tomorrow they will either release the last unit of the Necropolis or one of the 2 remaining units of Haven.
