Dude, I went to the First Ave. show this year. It was awesome. I'm on the mailing list so I got in on the first pre-sale (before the 93X pre-sale).
I've heard rumors that the Offspring will release a greatest-hits album and a new studio album in 2005, so there would likely be tour info around then.
