Microsoft is expected to reveal some of the details of its next internet browser.
Internet Explorer 9 (IE9) will replace Internet Explorer 8 (IE8), which was launched last year.
Steven Sinofsky, president of the Windows and Windows Live Division, will reportedly make the first details public.
"Through IE we aspire to give Web app developers access to all the performance and all the functions that the Windows OS and the PCs hardware will serve up. You'll hear tomorrow from Steven Sinofsky, and he'll discuss Windows, IE, and much, much more," said Ray Ozzie, according to Softpedia.com.
