It appears that Bethesda held a press demonstration of Fallout 3 in Taiwan, following which a number of Chinese and/or Taiwanese gaming sites have posted a report. This in itself is not remarkable from what can be gleaned (and I hesitate to quote from a Google translation), but the assortment of accompanying screenshots is. Among many other things you can see dialogue with Mr Burke, a talkative ghoul called Roy Phillips, and a balcony scene following the Megaton explosion. If you don't want spoilers, you should probably steer clear of these. It's been suggested that they violate the NDA a tad, so if you want to, look at them while they're there.

Here's a handful. There's a total of 145 screenshots available at the links below.
