Aluminum 7000 Series?

Interestingly when they announced the s6 edge plus and note 5, they were proud to mention that 7000 series aluminum was present which wade it much stronger than the 6000 series in the S6/Edge. Anyone know if this is present in the S7 lineup? I'd imagine it is since I doubt they'd downgrade, but I haven't heard anything official.
