Botcon 2008 Exclusive Grimlock and Jazz revealed and leaked Starscream prototype

Botcon.com has posted four new pictures revealing two figures in both modes from the convention exclusive box set for this year. I think Jazz’s colors and new head came out great. I wasn’t a big fan of the Cybertron Crosswise mold, though, so I’m not sure how excited I am about it.
 

The revelation of Grimlock puts the kibosh on the photo from taobao.com (?) of the black Grimlock as being the Botcon exclusive.

 

Here is the photo of the rumored black Grimlock:

Also, it appears that a prototype of the Botcon repaint of Cybertron Voyager Class Starscream has surfaced. He appears to be modeled very much in the likeness of Jetfire. You can see the auction here with lots of pictures. I’ve included a few of them below.
