So after the public announcement Citrix made earlier today, it was clear that they are going to bring back XenApp to life more or less. You can see more about the product here –>
Not quite, even thou it is called XenApp it is still running the XenDesktop FMA architecture beneath. The reason why they are bringing the XenApp name ? because of the brand, since many people are very familiar with the name and the concept it brings. Since many think of XenDesktop as an VDI solution.
It will again be available as the same versions that it was before, Advanced, Enterprise and platinum. Thus meaning the end of XenDesktop app edition (Since this is actually the XenApp functionality) Customers that have XenDesktop App edition have the same functionality as XenApp Enterprise 7.5
So what does XenApp 7.5 bring to the playing field ?
Hybrid Cloud provisioning – To AWS and Cloudplatform (No Azure here! will come later) gives the ability to provision XenApp servers directly in to the cloud provider.
And for existing XenApp 6.5 customers you have more mobile HDX funcionality to provider an better application delivery to mobile devices.
So for those that were hoping for a full return of XenApp, well it just marketing group that is doing a name change to the existing productline to use its branding to its full potential 
So the 7.5 product line is rumored to be released in the summer, is it going to be interesting to see what Project Merlin will bring besides the hybrid cloud provisioning
Also you can see what else is available here, it will be released in March
