343 has finally announced some File Share news for Halo 4!
Yes! We have updates about two things we’re currently working on in regard to the Halo 4 File Share.
• In-game search: We expect the in-game search feature to come online at the end of January (the 29th specifically).
• Web File Share: The Halo 4 File Share is coming to the web version of Halo Waypoint in late February.
For a recap about its current state of functionality, please refer to the 12.12.12 edition of the Halo Bulletin. We know many people are anxiously awaiting both things, and we’ll confirm their availability once they officially come online. – bs angel
