I haven’t seen any rumours about cameras, so I’m still wondering how you came to ask this question apart from the showing off an upgrade to colleagues part. We only know that 2018 will bring some surprises, and the context of that was back covers, not cameras.
I’ll have to note here that my employer at the time quite liked the idea of the Android 6 launch breakfast when that upgrade was introduced, the upgrade you’re going to show to your colleagues can also be a software launch done well!
