Germany coach Joachim Low is looking to integrate several more young players into his already youthful side with an eye on the Euro 2012 qualifiers and the tournament itself.
Five Dortmund players are vying for a place in Loew's long-term plans.
Team-mates Kevin Grosskreutz, 22, who has two caps, and uncapped 21-year-old Sven Bender complete the Bundesliga leaders' contribution to the national cause.
"Mats is more and more convincing with his style of play," Low said. "In the past four or five months he has made a significant step forward."
Low's choices will also boost interest for the game at Dortmund's Westfalen Stadium - site of their 2006 semi-final defeat in extra-time - with fans having already snapped up 54,000 of the 64,000 tickets.
"February 9 will be like a debut for me - it will be another great emotional moment after my return for Juventus," Buffon told his website.
Juventus forward Fabio Quagliarella, who impressed against Romania and had been one of Italy's form players in the early part of the season, is out for possibly the rest of the campaign with knee ligament damage.
Coach Cesare Prandelli's big hope for the future - Manchester City's Mario Balotelli - is also injured and was subjected to racist booing in the Romania game held in Austria.
A first call-up for Inter Milan's Brazil-born midfielder Thiago Motta also caused a stir in Italy given he represented Brazil at under-23 level. His inclusion still requires ratification from FIFA.
