"Terminator 4" in 2009?

Looks like the legal stuff has been sorted out. "Terminator 4" is heading to pre-production in the coming months and is said to be released in 2009. The fourth film in the legendary sci-fi series is said to launch a new trilogy, following the war against the machines. No word if Nick Stahl or Claire Danes will be reprising their roles.
Why? Why? And again, why? I was hoping the legal trouble surrounding this project would hold off this film long enough for no one to be interested, but aparently they're serious about getting this made. Apparently John Conner and spouse won't be the main characters this time around, but are in the script. Meanwhile, The Governator won't be the lead terminator, but is rumored to make a cameo. We'll see. They should have let James Cameron's masterpiece be as it were after the second film. Clearly I'm not happy about this whole, "new trilogy" thing. I try to convince myself that the first two films are the only ones that exist anyway. "Erk!"
