The answer is still: Yes, Opera does pass Acid2.
I don't know what the reports WaSP received about Opera and Acid2 contain, but the reports I have seen in the forums and desktop team blogs have all been based on misunderstandings, such as people scrolling or zooming the page.
Now, some vocal people have gone as far as publicly accusing us of dishonesty because of these misunderstandings. I think they should take the time to read the Acid2 page on what it actually tests. Some of the comments in the blog post at webstandards.org will also help to clear up the confusion.
If it had turned out that Opera didn't pass Acid2 after all, we would be the first to acknowledge the problem (and fix it). But people jumping to conclusions based on misunderstandings doesn't help anyone.
