I just refreshed the RPGNow website, and my two most recent Heavy Future releases popped up. At 9.99 you get Heavy Weapons, which is a HUGE collection of grungy, adults-only sci-fi and space opera spells, gear and magic items. Even if you're not playing Heavy Future, you'll probably want to pick this one up.
At 2.99 you get Dirty Galaxy, a collection of new diseases, haunts, traps and other hazards for a Heavy Future campaign.
Check them out, and expect some Black Tokyo stuff, as well as the POD version of Sentai Strike soon.
