From DarkHorizons:

DC Direct has released five maquette busts from its “Terminator Salvation” merchandising tie-in. The first four are of Kyle Reese (Anton Yelchin), the T-600, Blair Williams (Moon Bloodgood) and Marcus Wright (Sam Worthington).

What’s got everyone excited though is the fifth one – the T-RIP – which is blacked out and won’t be revealed until May 6th. The two guesses at the moment? It’s either Arnold Schwarzenegger, or John Connor (Christian Bale) as a Terminator, but McG has previously denied both rumors of those elements being in the film.
