Internet Explorer 7? – Unlikely
Nick Fink of Digital Web Magazine is advising users not to be too optimistic about Bill Gate’s comments at the 2005 RSA Conference about a new version of Internet Explorer for Windows XP SP2 users.
Bq. The release has only been identified as a security update, which means the rendering engine could still be identical to that in IE6 ("Internet Explorer 7.0, designed to add new levels of security to Windows XP SP2 while maintaining the level of extensibility and compatibility that customers have come to expect."). That said, I think it may be Fall before we see any new IE7 (non-beta) and I am not so convinced that it will be a standalone browser at all much less offer any improved standards support.
Looks like the Firefox developers have little to worry about.
