Yes, the Hpcwire article confirms 1.6Pbyte.

It also examines the core count:
"However, since Sequoia will be composed of 98,304 compute nodes and
contain a total of 1.6 million cores, one can surmise that a Blue
Gene/Q node will contain 16 cores. Whether this is implemented as one
16-core chip or two 8-core chips (or even four quad-core chips)
remains to be seen."
