Visual Composer future development

Hello,

in our company we are very interested in Visual Composer and we are considering move some application to VC, as well as use this tool for new developments within our Portal NW 7.3.

Thus, I am looking on official SAP info about future releases/developments/support and, in particular, on VC5/UI5 release recently announced.

Is there anybody who could give me some news ?

Thank you!
