The next month of JP hobby magazines with Transformers content, doesn't show much that hasn't already been revealed... but does show the upcoming United Rodimus having a remoulded engine block to allow him to have a Minicon plugged in (to mimic the Gen1 Targetmaster gimmick).
There are also pics of a set of three recoloured Minicons, which appear to be a JP exclusive or promo.
