The first images of the new Technic Set, Container Truck have recently appeared in a Power function PDF which shows that with the addition of the motorized functions (8293) it is possible to lift the blue container at the back.

Personally, I think that this type of should already include the motorized function, despite the price increase that would be certainly smaller that the cost of buying it separately. For now there are no additional details and the only certain is that it will retail in the beginning of 2014 or probably in Christmas in some markets.
