I completely understand your desire to have the latest updates. Rest assured, any delays keeping an Android version from your device have nothing to do with the release of a newer device model.
I want to advise against installing a software update not automatically pushed to your Verizon bought device that is not listed here: http://spr.ly/6601EnjdB
This link will also advise when the latest Note 9 updates become available. I hope this is helpful.
