There's only four weeks to go until the next IE9 developer preview, and it looks like Chinese leak site Cnbeta might have got its hands on the new build already.

I'm not quite sure what to make of the screenshots, nor the Google translation. The Developer Previews (Internet Explorer Test Drive) are not meant to have a user interface -- they're just there to show off the Trident rendering engine. That means we're probably looking at the beta version of IE9 in these screenshots. Does that mean the private beta has begun -- or are these simply fakes?

As you can see above, IE9 seems to gained a proper download manager. After the break there's a couple more images -- one of the very Chromeish 'new tab page', and one that hints at restartless add-on management.

Looking at the SunSpider performance graph, I'm not sure if these images are real -- or whether this beta build sports the latest version of the Trident rendering engine. When I tested IE's JavaScript performance last month, it was about the same speed as Firefox 3.6 -- not some 10 times slower than Chrome.

Very Chromeish, eh?

'Stay Fast'? Are these really from a beta build...?
