Fantasy Flight Games has announced the Into the Storm supplement for Warhammer 40K: Rogue Trader. From their web site:

Fantasy Flight Games is pleased to announce the upcoming release of Into the Storm, a supplement for Rogue Trader! You and your fellow Explorers have mustered the courage to claim the vast riches of the galaxy, but as the obstacles before you grow more formidable and your enemies more cunning, you’ll need a powerful arsenal to defend what’s yours. Arm yourself with the knowledge, equipment, and firepower to rise to dominance!

Arriving this summer, Into the Storm offers a host of new character options, allowing for increased personalization with the new expanded Origin Path and Alternate Career Ranks. Plus, play as a character from beyond the Imperium with two all-new xenos Careers. Keep watching, and over the coming weeks we'll reveal details of these exciting new options.

Vehicle rules add a new dimension to gameplay and expand possibilities for adventure. Explore uncharted worlds in a Rhino APC or dominate your foes from the cockpit of a Fury starfighter. You can even gain access to an extensive new armoury of weapons, armour, and gear wrested from alien races or rediscovered from humanity’s dark past, or augment yourself with new psychic powers for Astropaths and Navigators.

I got Rogue Trader for Christmas, and I'm looking forward to a playtest of the game. Heck, I could easily see this game becoming our weekly game once Star Wars runs its course -- I think my group could have a blast with the sort of galactic sector-building adventures that Rogue Trader offers. As for the expansion, I haven't read enough of the Rogue Trader core book to say if it's really needed or not; my sense is the book was complete enough as is, but then again, what gamer doesn't like more options?
