All of our packs are available on Linux as well as Mac/Windows. If other packs aren't then that is something you need to addressing those authors about. We've stated all along that there will be a 'solution' for Linux users to play our packs. We've never said that that way will be the Curse app (although that is the hope).
In terms of official news, while there has been, and continues to be, a lot going on behind the scenes. There is very little news that can be announced. We do plan to have a Town Hall reasonably soon to make the announcements that we were unable to make at Minecon. The situation with the launcher remains unchanged at this time though.
I don't understand yet why the saying on the main page was yet not fixed, like Slow said he would do and that it would be simple to do, on reddit. I don't understand why the Linux launcher is being called legacy, when it is the only option(it has gotten people confuse since day one). And I don't understand the lack of communication, ftb is acting almost like Microsoft acted when Skype stopped to work on Linux, and then came the "alpha version" that only works between Linux users.
