We don't know about any, probably san diego comic con in a few weeks. Mirage and soundwave were listed in the walmart computer system a few weeks back
Hasbro said they were going to wait after the movie for the big reveal, my bet is SDCC. Regardless, none of these have been confirmed (I think several Soundwaves were found in directory listings or whatever).
Leader Megatron is speculative at this point. Deluxe Soundwave and Human Alliance Soundwave have been found listed in Wal-mart computers. I'm pretty sure Mirage and Wheeljack were listed as well, but not by name.
I hope Mirage isn't incredibly hard to find for months when he comes out. I reaaaally want that Ferrari...
Honestly, unless the next wave has a crazy ammount of toys. (Which I doubt.) The only way you wont be seeing your Mirage, is if they pull a RTS with the movie like. But, it's the movie line... do you really expect -that- to happen?
Out of the toys we know and ones we're presuming, the only things left I want are Space Case, Deluxe Soundwave, Deluxe Mirage/Dino, Deluxe Skywarp, and... I think that's it.
Even tho I think the reveal will be at SDCC I would love to find out early via leaked test shots.And honestly I don't know why Hasbro is being so damn secretive about figures lately,its as if they they are almost afraid to,probably because when they do reveal them as Repaints Repaints Repaints that people are gonna freak out at no new designs.Just sayin.
