Does anybody knows when the RFQ functionality in collaboration with vendor will be available for Dynamics 365 Finance and Operations?  I meant like it is in AX2012 R3 when a external vendor can answer RFQ from the vendor Portal? 

I am familiar with the new Vendor Collaboration of Dynamics 365 related to purchase order confirmations, but the RFQ flow is no available yet... The only post I found was this  "In AX2012 vendor portal lets you collaborate with or notify a supplier, and also lets you upload requests for quotation (RFQs) and allow vendors to respond to them"

But I am not so sure if this is going to be in 365 or more important when?
