The multi user support for education is huge. I wouldn't be surprised if it gets announced at WWDC for all iPad owners. If they figured out a way to do it for education it can't be that difficult to for everyone.
My guess is Apple will have a spring event highlighting 9.3 with a new phone announcement and maybe new Watches/Macs too.
