Yeah, there's just the Optimus and Bee that transform. There's a non-transforming Bumblebee too. They're all really nice representations of the vehicles though.
The first three were out in Australia last month, and the non-convertible ones look better than the transforming Bumblebee... I didn't buy any, so just took a lot of photos of the ones in the store.
How are they? I wouldn't mind a Lockdown, and possibly Drift. I'd probably just attach a GoPro on them anyway to shoot video while remote-controlling them
