MacOSRumors echos rumors that iChat will be gaining video and voice functionality next year... along with added codec support provided for Quicktime streams.
They also believe a Apple-branded Chimera-based browser will be released next year. Speculation on such a project was sparked by David Hyatt's employment at Apple in July.
Long-time Apple fans will remember that Apple had marketed their own browser years ago - Cyberdog... which was subsequently discontinued along with their OpenDoc technology.
Spymac first posted rumors that Apple may break free from Microsoft IE as soon as MacWorld SF - but did not specify which browser they would migrate to.
