That WAS Internet Explorer 9, but the online community made such a ruckus (with good reason) that MS would use the "standards compliant" mode only with a nosuck tag, that they went ahead and made it the default and you'd have to opt-in to the sucky mode.
IE9 should be standards compliant by default. A patched version of IE6 however should continue to be sucky by default and use a new rendering engine only with a nosuck tag.
