If you have not seen the upcoming space set for Dyson Sphere Joint Command, the "energy weapon" is a single-cannon that can benefit from beam and cannon boff powers when you have 2 and 3 piece bonuses from the weapon set.
How many sets will pass before we have an energy-torpedo that can use energy and torpedo weapon powers?
And how many before energy and torpedo boff powers are combined?
Well, whilst not QUITE what is being described, we do essential have two steps in this direction already:
The bio-neural warhead, which is (for all intents and purposes) a torpedo with the ability to use an energy weapon
The VATA console torpedoes, which (depending on which you use) have the ability to fire smaller torpedoes.
I can't imagine that they won't expand on this.
Sidenote: The bio-neural warhead is ridiculously overpowered when used on shuttles in shuttle/fighter only missions. It can kill enemy fighters before reaching them, and then will switch to new targets constantly, firing off it's point defense at anything nearby =P
Wasn't that the episode where Jadzia went down like a fish? I mean, really, great character who figured prominently in the storyline. Someone like that should die heroically surrounded by a mound of enemies, not surprised and gutted by some peon klink redshirt. What a waste.
