I know it is almost 3 months away but am very excited for this tie. First I want to say that China is VERY VERY LUCKY to have luck on our side when we avoided drawing Russia or France, each who will be anchored by Top 10 players in singles. Also we are lucky to be able to play this tie in China.
I guess the tie will probably be in Beijing

What other facilities in China meet the Fed Cup requirements of seating 6,000 people? Maybe the Masters Series Final venue in Shanghai?
Next about the teams, Germany will probably field Top 15 Groenefeld, Schruff, Muller and Woehr.
China will probably go with Na, Shuai, Jie and Zi again unless Sun / Li win Roland Garros or Wimbledon

. But I don't see how Jie can be left off the team because she is the highest ranked Chinese player and has a win over Groenefeld in 2006.
I think China has a big chance to win and be in World Group I 2007. Groenefeld is not unbeatable by any means and she is very inconsistent. We don't even need to beat her if we can win the other 2 singles because we will probably win the doubles. Groenefeld is a world class doubles player but her compatriots are not.
