In-hand looks at TR wave 5 Voyager & Titanmaster

The first of the fifth wave of Titans Return toys were apparently available at one of last week's Movie Toy launches, which were Voyager Blitzwing and Octone, and Titanmaster Ramhorn.
Each of these are mostly redecos of previous toys... with Blitzwing and Octone being the "real" version of those moulds, as the "redecos" were effectively released first to improve the sales potential of the redecos (it is highly unlikely that those two toys were designed to be Optimus and Megatron, and Hasbro then decided to redeco them into Blitzwing and Octone/Octane).
Ramhorn is a remould of Shuffler, with a new head and weapon-pods.

Some photos of each can be seen here.

These shouldn't see a full release until the end of this month or early June, but might start showing up in other Asian countries in the next few weeks.
