It looks like our brilliant plan to stop playing Halo 2 (which was helped along by Microsoft's removal of Live support for Xbox 1 games) worked! According to a deleted Facebook announcement from Xbox Germany, the friend list cap on Xbox Live is being boosted from a paltry 100 to a ridiculous 1,000.

Strangely, neither the embiggened friend list cap nor the "Finder tab" are present in our preview version of the upcoming Dashboard update.
