This upcoming re-release of the Dinobots could be a revision case of wave 3 that includes some of the toys that are new to wave 3 (the Terrorcons and Firestar), or a "new" wave with all older toys (noted as wave 4 on the master carton), which is rare, as it is hard to sell a new wave to Retailers if it doesn't have any new product in it (they usually only do this when a series is more popular than expected, and Retailers are wanting more product of that series to fill the shelves until the next series starts).
