What is also interesting is that from looking at the images we can see what appears to be a new Genestealer Broodlord on the front cover of the Tyranids Painting Guide. Whilst it bears some resemblance to the Space Hulk Broodlord it does appear to be a new miniature. You can also see an artists rendering of the miniature on the front of the Leviathan campaign book.
So what does all this news suggest? Well it is strongly pointing towards a starter set similar to the Stormclaw set released as part of Sanctus Reach. Seeing the new Broodlord may even be an indicator that this will be one of the included special 'characters'. If this is correct I wouldn't be surprised to see this before the end of November.
