Opera 8.0 will not render the Acid2 test correctly. The test was announced on April 13th, the day after we finalized our code for 8.0 final. So, we could either delay 8.0 final even more, or ship as is. We decided (rightly, AFAIAC) to do the latter. As of now, we have no plans to disclose when we'll render it correctly.
See, the Acid2 test isn't a race to see who can render it first. I'll give a hearty congratulations to the team that gets it rendered correctly first, whether it's Opera, Safari, Mozilla, Microsoft, or anyone else, but that's not the point. The point is to make sure all browsers will render Web sites consistently. The point is to give Web developers a common baseline to work from. The point is to make the Web a better place.
Yes, I'd like to see this happen sooner rather than later. But any team that's working on fixing the bugs or adding the features necessary to render the Acid2 test correctly is showing a commitment to the Web. Can we please stop making this a war between browsers and start making it a win for the the Web? Thanks.
