SPS Requirements - HANA 2.0 und SAP HANA DW FOUNDATION 2.0

I'm trying to find out which SAP HANA DW FOUNDATION 2.0 SPS I require for HANA 2.0 SPS 02.

HANA 2.0 SPS 02 was delivered in July 2017.

Do I now need SAP HANA DW FOUNDATION 2.0 SPS 02? This version is not yet available and I do not know when that will be.

Where can I find this release date?

Or will SAP HANA DW FOUNDATION 2.0 SPS 01 suffice?

I had hoped that this information would be available in the PAM but it wasn't.
