I am not aware of any special licensing for NSX for Horizon View. You have the three editions and then you have licensing based on CPUs or based on VMs. So it really depends on the license edition you're buying (which will probably at least be Advanced, so that you have microsegmentation). Also it's probably a good idea to go with VM licensing for Horizon View, so you can scale up / scale out your View servers if needed, without the need to purchase new licenses.
(It seems that my conclusion might be wrong): NSX licensing changes - ITQ
NSX for horizon has been rebranded to NSX Advanced for desktop. This means that if you buy the per-user license of NSX for horizon view you will always get the advanced license of NSX, which should be sufficient for most horizon use cases that require NSX. The only thing that would be a nice improvement is to include the Cross-vCenter NSX feature in the NSX advanced for desktop license, considering how much effort VMware is putting in the horizon view Pod design.
So there you have it
There are NSX Advanced for Horizon and NSX Enteprise for Horizon
For customers that has existing NSX for Horizon, you will be eligible for NSX Enteprise for Horizon.

Thanks for the replies, but I continue with a doubt yet. The features of NSX Enterprise for Desktop are the same of the NSX Enterprise version? I didn't found any paper with features of NSX Enterprise for desktop =/
From a technology perspective, there is no difference between NSX Enterprise and NSX Enterprise for Desktops. It is all NSX for vSphere. The difference between the two is the licensing. Much like vSphere vs vSphere for Desktops, created in order to make VDI more cost effective, the only difference is the name on the license key, and the way license are tracked (CPU vs Desktops). I work with organizations who have purchased NSX for vSphere, and work with folks who have purchased NSX for vSphere for Desktop. The download and install are all the same.
