either they are now trading one plus one for next versions (Exchange ) Or Marsh mellow update .. It doesn't seem to be a teaser more of a itch.

as the picture shows one plus one, it might be marshmallow update or Oxygen OS coming to the device.
We can't live without OXYGEN (Oxygen is the OS of oneplus) and .............. ?????
[Any other oneplus related product?]
My guess would be it's a tease for updates to HydrogenOS and OxygenOS (which have been a LONG time coming - I switched away from CyanogenOS because I thought its updates were too slow haha). Together the elements make water which you definitely can't live without.
Plus I believe they've previously said an update would be coming in the new year, here's hoping for marshmallow-y goodness
