I don't even think we'll see info about "what's next" at Comic Con - perhaps things like Plo Koon's Starfighter, the TRU exclusive Jedi Starfighter w/Obi-Wan and the final versions of both the later Evolutions and Battle Pack assortments with packaging samples - but beyond that, I doubt it will be anything more than a scaled down version of the displays at C3.
I think we are in for (comparatively) a bit of a dry spell come August/September anyway.
No more unleashed beyond the EP3 Wave 2.
No more 12" figures at all.
No more Deluxe figures once Wave 3 hits with all of it's different case ratios
We've already gotten figures #1 - #47 so that leaves only nine figures and at their current pace those will be all out by the end of July, perhaps early August.
That leaves only the 500th Vader, the three Evolutions sets and the three Battle Packs.
As far as I'm concerned, a break this summer would be welcome after the April/May onslaught we've just been through. I mean really - who could have guessed that we'd already have 47 basic figures, 14 deluxe figures (I'm counting the paint variants of the Vulture Droid and Clone 3-packs separately), 6 unleashed, 5 12" figures, 3 battle arenas, the Mustafar playset, three small vehicles, four mid-size vehicles and two large vehicles all within a two month period since the official release date!
