Looks like McG's powers of persuasion have done their job-- Arnold Schwarzenegger, as we pretty much all suspected, will be back in Terminator: Salvation. This confirmation comes from Terry Crews, who has a part in the movie but isn't exactly the last word, so don't be surprised if further denials come down the pipe. But Crews sounded pretty confident talking to MTV News, saying "That's it," when they mentioned Schwarzenegger's participation.

Really, it's hard to imagine how they'd do it without him. The whole plot of the movie seems to be Skynet's work to build the T-800, and the payoff of that is obviously the reveal of Schwarzenegger. McG has already admitted they'll be using CGI to make Arnold look like his cut, 1984 Terminator self, so now all the mystery that remains is at what point in the story he'll show up. Something tells me that's still enough intrigue to get us into theaters.
