Dingbatt:Presso: On Spark and am downloading 5.1.1 (O.T.A) as we speak so its out there if you want to check.
What is the build number you ended up with?
(Settings->About device->Build number)
As I said above your post I hope the update process isn't going to be too painful with a rooted device. I have downloaded Smart Switch for PC but I understand the update removes root so I need to weigh up what is more important.
Build number is LMY47X.G920IDVU2COGA
