Today during keynote, @BillRMcDermott announced that SAP Fiori and SAP Screen Personas are now included in the regular SAP License.
See Press release here:
This is very important to help solidify the SAP strategy of UI renewal.
SAP customers are often slow at adopting new UI solutions. See the adoption rate of Netweaver Business Client for example. Having both Fiori and Personas now included in regular SAP licensing is a great initiative.
