http://www.seibertron.com/transformers/ ... oll/30192/They often pick reasonably recent moulds and usually something G1 related or similar.
I guess we can rule out anything already a possibility for any further Tomy Mall exclusives/ E-Hobby exclusive (cloud toys).
I can't see them throwing out an Adventure toy as an Exclusive - unless the box that goes with it happens to be about say Transformers Prime - then if it was then I guess a Blue BH Smokescreen would be rather nice to have.
G2 is quite trendy at the moment so there is the other Smokescreen - and that does complement the existing Dreadwing well too. and we are not far off another masters period - perhaps they might pick something like GoShooter sometime.
Alpha Trion was actually a bit of fun too.
I think they might consider using the missing from Japan Combiner Wars Moulds too like Rook, Off Road & Alpha Bravo (or the Victorian variation of the Helicopter) for something.
I expect one day we might get Deep Cover, Clamp Down and Detritus too from some source or other using Combiner Wars Moulds.
I suppose you can add Exhaust and Slicer (from Combiner Wars Wheeljack) or Sideswipe (from Sunstreaker) to the list too.
But they show little interest in making new heads so I guess the question is -there a suitable head that can double as Red Alert or Sideswipe Deep Cover or Clampdown if needed to.
Personally I'd love to see a G1 mould like the unused Sunstreaker like Police car to give it some Transformers Character legitimacy like they did with the Silver Honda City as Crosscut already.
P.s.
I think the Omni-bots idea would be rather well suited to one of those Asian exclusive boxed set or a Platinum set since there is 3 of them.
