The future of WebDynpro Applications?

Hello Gurus;

I just wondering, with the introduction of SAPUI5, what should we expect from WebDynpro's ?

I know Web Dynpro are used in SRM and CRM, but additionaly, what modules make use of this technology?

Also, as far as I know, the User Interface Add On 1.0 for SRM 7.0  is not build in WebDynpro's , so it seems that this technology  is soon to be obsolete.

¿What are your thoughts? Makes sense to get certified in WDA at this point?  on what SAP modules are WDA using, aside of SRM and CRM?

Thank you for the comments.

Best regards
