Does this really even matter?!?

Finally Confirmed: Arnold is in Terminator Salvation
MTV caught up with Terry Crews who put all the Arnold Schwarzenegger cameo in Terminator Salvation rumors to rest once and for all.
Unless Crews was drunk or didn’t realize the calendar wasn’t on April 1 during the interview, Arnold is in the movie. Done deal.
Crews’ exact words were “That’s it. And so am I” when asked about the possibility of he and Arnold appearing in Terminator Salvation. “There are a lot of guys in that movie. I mean, Terminator 4 is very big.”
Crews went on to state that Arnold is also lined up for a cameo in The Expendables which is currently shooting down in Reno with Jason Statham, Sly Stallone, Eric Roberts and Steve Austin. “I am not at liberty to discuss what kind of cameo it is [in The Expendables], but I know for a fact he wants to be down,” Crews explained. “Arnold and I did a movie together a long time ago called The 6th Day. Arnold and I are cool; he’s the best.”
Will Arnold appear in T4 already a T-800 or will we see the human character the T-800 was based off? I’m thinking some CGI wizardry will be put into place so we see a “young” Arnold just as he appeared in the first Terminator. I’d plunk down $10 for that alone.
