All the fire sets have Fire in the name, except Thermal Radiation. All the ice sets have Ice in the name, except Cold Domination. Support set names don't follow any pattern, for whatever reason.
What? The Ourodev people aren't the ones in conflict with Homecoming, and the guy who leaked A) cannot, to the best of my knowledge, code and B) has left the community altogether. Many of the servers that run Ouro's code don't like HC very much, particularly coxg, but they're not Ourodev.
This is not true; they also transferred the copyright internally in May. Neither has any impact on how NCSoft has every legal right to shut Homecoming down if they really want to.
I imagine that if Jimmy were to say anything, he'd say "it's just a trademark refresh, everyone calm down". Of course, by acknowledging a non-story, you make it a story! :P
I don't think it's anything to worry about - they already own the game, we all know they own it, they don't need to do anything to shut us down other than send a C&D. It's a non-story.
I don't know that their first line of attack would be to do that, anyway. I am not a lawyer, but I suspect they'd be happy enough if the team generic'd all IP-infringing characters and agreed to continue doing so going forward. In other words, I don't think it's an existential threat in the same way that NCsoft is.
