The latest wave of Rescue Bots "rescan" convertible bots have been found at American retail, which has the new jet Bumblebee, new dragon Heatwave, redeco t-rex Optimus and redeco raptor Bumblebee.
They were released on Amazon America a couple weeks ago, so they didn't take long to appear at retail there.

These should show up here eventually, but first we should get the previous wave with the new toy Brushguard (turns into an ATV).
