Besides the stuff we've already seen so far from Comic-Con, Hasbro has more Titanium Series prototypes that we are allowed to show you, but the catch with these is that not all of them will get made and you get to help determine which ones are produced.
Hasbro knows that the SSG readers are able to comment on each photo in the SSG Photo Database, there's a comment box beneath each photo, and they want feedback on the items shown. There are mini-figures, 3 3/4" figures, Action Fleet-sized 6" Titaniums, Titanium Playsets, mini-dioramas, even Hot Wheels-style die cast cars. And you have to comment on each photo in the prototype database and let Hasbro know what you think of 'em. That's the key to getting the Titanium Series items you want (and possibly don't want) made - you have to comment on them.
Here is the prototype gallery, this gallery is ONLY of the Titanium Series prototypes that we're talking about here, so comment on each and tell Hasbro what you really think, the more users that comment the better the chances for the fledgling Titanium Series line.
