End of Service (EoS) and Withdrawn from Marketing (WDFM) are 2 different 
things. The former is when IBM will stop 'servicing' e.g., maintenance/provide 
parts of/for the System. The latter is when IBM will stop selling any upgrades 
(MES) etc. Upgrades requiring physical components or just Licenced Internal 
Code (LIC) could have different dates for WDFM.

z13 and z13s are as yet not EoS.

As it has already been mentioned, this URL is an excellent reference for 
various dates:

IBM Mainframe Life Cycle 
History<https://www.ibm.com/support/pages/ibm-mainframe-life-cycle-history>
Each family of the IBM Z mainframe hardware products has followed a similar 
life cycle pattern: product announcement, general availability, marketing 
withdrawal, and service discontinuance.

that would be nice - but now with z13 and z13s processors you cannot
even get IBM to perform any hardware changes since those boxes are
EOS....I think last June ?

we were somewhat lucky the processors are already IN THE BOX so an MES
of our Z13s was done in May before the EOS date to add a second zIIP
processor
