In the recent Figure King magazine that has shown us a lot of nice new images of upcoming figures, there was a scan of a Bearbrick that transforms into Optimus Prime.

For those unfamiliar, the Bearbrick line has been featuring bears done in themed or licensed colour schemes, including some Transformers coloured bears in the past.
Now it looks like they are going a step further by having one of their bears be convertible... but I cant tell if it is a TakaraTomy product, or a licensed product done by Bearbricks.
Either way, it looks like it is being included in the 30th Anniversary celebration, like the Neon Genesis and Sega crossovers.
