Now that BotCon has revealed the main Transformers exclusives for SDCC this year (July), the official pics have been released.
- Generations Combaticons (packed in Bruticus mode in a big box - released 2-3 months before their retail release, in different colours).
- TFPrime Terrorcon Cliffjumper (First Edition mould/redeco originally planned for regular release, now specially packed, with a shard of dark energon).
There may be other items, announced later (last year had 4 items - only 2 were actual Transformers toys, the other two were products from other lines, done in a TFs deco).
Also note that SDCC 2012 has another GIJoe exclusive toy done in a Transformers theme - Shockwave HISS tank.
