Just like the TFPrime "Titans" (Optimus and Bumblebee), the Beast Hunters Titans look to be released after their toy series has ended as well.
(how can such simply designed and sculpted toys take so long to make?)
And just like the TFPrime and Movie Titans, these ones make Actionmasters look awesome in comparison.

There look to be four of them - Bumblebee, Optimus, (Sharkticon) Megatron, Shockwave.

Said to be the "16 inch class", which is the larger Titans (the smaller ones are 12 inch).
