Only on the first day, and they are yet to have the Hasbro presentation (which might deserve its own news topic if it reveals a lot of new good stuff).

The big news so far from the pre-Con breakfast is the new Combiners that were teased at BotCon last month... featuring Superion and Menasor (each with four Deluxe toys and a Voyager that comes packed with a Legends figure that either becomes Superion's gun or Menasor's chestpiece)
News of that is in its own topic here, for your comments

Generations and Masterpiece Transformers display

Movie Transformers display

Kreo display

Angry Birds display

Sideshow Collectables (very expensive) statues display

And something rather unusual... a Transformers themed guitar, to match the style of the SDCC Rockband 4-pack... which attendees of SDCC can win.

Just like at BotCon, Hasbro are likely to add new items to their display cases after their presentation... which is within the day I think. So by the end of today we should see a lot of nice new toy photos.
