It's also really worth differentiating the game from the component quality in this case. A lot of the ships fly differently, work in cool combinations that are a bit more creative than what you get in X-wing because there's less incentive to balance it for tournaments, and Andrew Parks, one of the designers, has been very active on BGG answering questions, updating FAQs, and generally just being responsive. I guess that's more to do with him as a person than WizKids, but that kind of support isn't something I've ever seen before and really won me over.
I'm probably not going to get the regular groups or quite the level of community play from this game, but it's definitely a lot of fun, and the greater emphasis on missions is also a nice change of pace. It gets a lot of the feel of the different factions right.
As far as swarms go, people talk about it, but I don't see it happening. The science vessel and d7 swarms people predicted don't seem to really work with the relatively high attack to defense dice ratio in the game, and you could potentially put 5 base Jem'hadar attack ships out in October, but I'm skeptical about it being all that great and doubt many people will even care to do it.
