Here's the important bit: 

Q. When SharePoint 2013 RC was released, there were new versions of InfoPath and SharePoint Designer at the same time. Will SharePoint Server 2016 RC include new versions of those products as well?

A. For the past decade, InfoPath and SharePoint Designer have been at the forefront of Microsoft solutions for professional developers and information workers building lightweight business applications for the enterprise. SharePoint Server 2016 extends our commitment to lightweight business applications.

As we continue to evolve, we recognize the need for a long runway as we augment existing business app offerings with new tools and capabilities. As a result, we’re updating the support timelines in conjunction with SharePoint Server 2016, specifically:

• SharePoint Server 2016 will include an ongoing capability to host InfoPath Forms Services. InfoPath Forms Services on SharePoint 2016 will be supported for the duration of SharePoint 2016’s support lifecycle.
• InfoPath Forms Services on Office 365 will continue to be supported.
• InfoPath 2013 and SharePoint Designer 2013 will be the last versions of those products. SharePoint Designer is not being re-released with SharePoint Server 2016, although we will continue to support custom workflows built with SharePoint Designer and hosted on SharePoint Server 2016 and Office 365. Support for InfoPath 2013 and SharePoint Designer 2013 will match the support lifecycle for SharePoint Server 2016, running until 2026.

So if you're looking at long-term strategy, I think the message is InfoPath and SP Designer are toast for whatever follows SP 2016.
