Coming to America soon is another set of RID Happy Meal toys at Mcdonalds.

This time there are four characters (Optimus, Bumblebee, Thunderhoof, Steeljaw), but each one looks to be given out as a pair of Robot and Vehicle.
Or, there will be eight weeks of toys, with each vehicle and robot being released separately.

We got some of the first set here in October last year, so these might come here too later in the year.
