Microsoft Internet Explorer 7.0 Details Begin to Leak
Sources say that IE 7.0 – which is code-named “Rincon,” they hear – will be a tabbed browser. IE 7.0 will feature international domain name (IDN) support; transparent Portable Network Graphics (PNG) support, which will allow for the display of overlayed images in the browser; and new functionality that will simplify printing from inside IE 7.0, partner sources said. The new browser also will likely include a built-in news aggregator.
Thank god…I’ve been begging for support for transparent PNG’s for how long? 
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.
Oh dear god, don’t do this to me guys… This is the only reason people (well ok, just nerds and web developers) will return to IE, otherwise it’s on to bigger better things like Firefox.
