I finally got a pic of all 3 of the ones I found together:
Size wise, they are about 6 - 6 1/2" tall. Bigger than the revoltech's if my memory serves me right.
Price on these was $11.96 each @ Wal-Mart. I've heard they are $12.99 @ K-Mart but have not seen them there yet.
I'm actually really impressed with these. The pics I saw of them online didn't do them justice and I'm really looking forward to the next wave.
Out of the 3 I found, the Bumblebee is definately the best of the bunch. Barricade is also really nice but Megatron is lacking. Compared to the other 2, his paint just seems "blah". The one cool thing about him though is he comes with the Arm Mounted Fusion Cannon that looks just like it did in the movie. Very nice touch. In fact, all of the weapons that these come with look just like the weapons in the movie.
I really hope this line does well and hopefully we'll see a Ironhide, Ratchet, Starscream, Blackout, Bonecrusher and Devastator!
