Microsoft announced the features of the June update of the Xbox One system software for preview members yesterday, but the first patch is somewhat smaller, as indicated by the full patch notes released in the private preview forums.
Program Manager Emily Hanson also mentioned something interesting in the private preview forums, teasing something "*BIG*" coming at E3.
CD Projekt Red's community and website coordinator Marcin Momot confirms that the patch that would fix the frame-rate on the PS4 won't arrive this week. Aside from a frame-rate fix the patch will adress as much as the team can. The developer is listening to everything the community is reporting.
