Safari 5 to join Steve onstage Monday for WWDC?

According to a report from French blog MacGeneration, one of the announcements on tap for Monday's WWDC 2010 keynote (which we'll be covering live, by the way) is a major update for Safari -- namely, version 5. If you believe the docs the site has obtained, there are more than a few big changes coming, including Bing now alongside Yahoo! and Google search options, a new "Safari Reader" for better / easier RSS reading (we're hoping they're taking a cue from Google on this), 25 percent faster JavaScript performance and DNS prefetching (hello, Chrome), improved HTML5 support (no big surprise there), and new developer tools which we assume will be along the lines of Firebug or Chrome's developer helpers. So we hope. The update will allegedly also add hardware acceleration for Windows PCs, an address field that auto-predicts URLs (they're calling it a "Smart Address Field"), and a handful of other minor tweaks and snips. Furthermore, there's an expected minor bump to Snow Leopard (10.6.4) which will resolve some nagging issues, though nothing really more than that. As we're sure you're aware, the next 48 hours or so are going to be filled with all sorts of nutty rumors about what's happening at Monday's keynote -- we'll try and separate the wheat from the chaff for you.
