The Warhammer 40k MMO is still very much in development. Although it isn't really "news" so much as a reaffirmation that Vigil Studios was still working on the MMO, the official word comes from THQ in their official quarterly report. Here's the teeny-weeny mention:
Our other initiatives include our WWE online game being developed in Asia and our Warhammer 40,000 MMO game being developed at our Vigil Studio.
We think the popular Warhammer 40,000 Sci-fi universe is a great fit for PC MMO gaming.
It's not much, but it definitely sounds like they're still engaged with the product. You can read the official THQ report here.
