By my understanding, both have already been released.

The first bolded is the mention of 'preset parties' in which you tick off an enemy leader, the entire group links to you and gang rapes you.

The second is connected to the text after the bold as well. Effectively - the number of the enemies that respond to the 'call for help' is in direct relation to the number of allies you have by your size and your collective strength. A full party of 8 is going to have to deal with a lot more straight links than someone going solo, who will likely just have to face individual aggro without links.
