Tintri is a classic example of "not doing enough when you have the lead" - Which is a shame since I like the product.... They were doing VM reporting before some others were even vSphere aware.
As for a buyer? Nimble went around the houses before being bought by HPE. The only place I could really see them going to is Lenovo (where they would die a slow, horrible death).
Dell? - EMC thank you
NetApp? - Solidfire
HPE? - Nimble / InfoSight
HDS / Huawei? - They Prefer to develop in-house.
Cisco? - They have been burnt before (Whiptail) and personally I think NetApp would be a better option for them...
