Titanium
The 6" line has been canceled and Grimlock and Prowl are said to be the final new molds released, though no schedule has been revealed. Molds for several unreleased figures were on display at the 2007 Botcon, and it's possible they may be released as part of other toy lines. They included Cosmos, Arcee, Shockwave, Silverstreak and War Within Bumblebee (along with a Cliffjumper head). Grimlock and Prowl where released in August of 2008as ToysRUs exclusives. A Thundercracker redeco for Skywarp was released as a SDCC exclusive also available from Hasbrotoyshop.com. Currently this is the end of the 6 inch Titanium line with all other prototypes being shelved by Hasbro. During a panel discussion at BotCon 2009, a Hasbro employee stated that there are plans for more figures in the Titanium line to be released. 2009 saw the release of 3 redeco 6 inch figures as Target store exclusives, under the name label Transformers: Universe Titanium Series.
