It was somehow clear that InfoPath doesn’t have the brightest future after being the only part of Office 2013 that was not revised. Now it’s official – InfoPath will be retired and there will be no future version: http://blogs.office.com/2014/01/31/update-on-infopath-and-sharepoint-forms/
I’m quite curious about what the new roadmap will be – SPC2014 will tell us…
