Well, Forgeworld have produced another addition to the Hive Mind in the form of the Malanthrope.

There are also more ripper models, and a Brood Nest
Looking at the stats, I can see this being useful for replacing a Winged Hive Tyrant (ie now we can have the equivalent of two of them), unfortunately it doesn't count as an MC, however the instant death rule is very nice. And the model is reasonably priced, and looks alright. Not as beautiful and sexy as the Trygon, but still excellent.
