I think it will take longer than that! The current stable version of Safari (version 3.1) scores a 75 on Acid3 while the beta of OmniWeb 5.7 only gets a 41. I can understand OmniGroup not tracking pre-release versions of WebKit, but I'd at least expect them to keep up with Safari. Wasn't that the whole point of moving to WebKit, to get all the Safari improvements for "free"? I don't understand why OmniWeb is lagging behind.
