Microsoft are retiring InfoPath and investing in new forms technology across SharePoint, Access, and Word. This means that InfoPath 2013 is the last release of the desktop client, and InfoPath Forms Services in SharePoint Server 2013 is the last release of InfoPath Forms Services. The InfoPath Forms Services technology within Office 365 will be maintained and it will function until further notice.
My recommendation is to look at using Nintex Forms: http://www.nintex.com/en-US/Products/Pages/NintexForms.aspx
