Sources say it will include tabbed browsing like other popular browsers but here is the part I didn't like:

Partner sources say Microsoft is wavering on the extent to which it plans to support CSS2 with IE 7.0. Developers have been clamoring for Microsoft to update its CSS support to support the latest W3C standards for years. But Microsoft is leaning toward adding some additional CSS2 support to IE 7.0, but not embracing the standard in its entirety, partners say.

This shows Microsoft as "snubbing" the standards and other browsers and basically says that "as long as we are the most popular, we will make our own rules, and to heck with everyone else."

Why doesn't this surprise me?

I noted an article on Cnet this morning that tells of a challenge to Microsoft from the Web Standards Community called the Acid2 test. This "will be sponsored by the Web Standards Project, which is a grassroots coalition fighting for Web standards.". Part of what this test will include:

"We will produce a test page, code-named Acid2, that will actively use features Web designers crave, such as fixed positioning of elements.

Fixed positioning is described in the W3C's CSS2 Recommendation, to which Microsoft has a "deep commitment." However, fixed positioning has been supported for years by all modern browsers except IE for Windows. "

Naturally there will be other items tested. It has been said that this test might even identify flaws in other browsers.

I won't be "holding my breath" waiting for IE 7.0 to pass this test.
