Its delayed for now, no new date has been announced as of yet. Should be no longer than 2 weeks.
UPDATE 2 (January 29):
We have received news that the Home 1.75 platform update has been delayed to finalize details of the roll-out. This is a big, important update that will bring a lot of long-term benefits and requires a little extra preparation. We will provide you with further updates as we receive them but are hopeful that the delay will be no longer than two weeks.
It was CANCELLED i guess they figured they made a Mistake somewhere... Good thing then... We don't need to loose our stuff...
