Oh this sounds good news! I love Opera and it's the only browser I tend to use day to day because of the speed, features and sticking to the standards more than the others. Indeed this post is being written for 9.5 beta on the Mac. I wish you lots of luck on this one as I'm very keen to download it for my new N810.

Btw. Have you asked Opera themselves? I have always found them approachable and clever people.
